TUESDAY, APRIL 29, 2008
U.S. Senate,
Committee on Environment and Public Works,
Washington, DC.
The full committee met, pursuant to notice, at 10 a.m. in
room 406, Dirksen Senate Office Building, Hon. Barbara Boxer
(chairman of the full committee) Presiding.
Present: Senators Boxer, Inhofe, Lautenberg, Klobuchar,
Whitehouse, Barrasso, Craig
OPENING STATEMENT OF HON. BARBARA BOXER,
U.S. SENATOR FROM THE STATE OF CALIFORNIA
Senator Boxer. The Committee shall come to order. We
welcome our panel and our honored guests who are here today.
Today we will hear about the risks that toxic chemicals
pose to our families and communities. Most at risk are
children, pregnant women, the elderly and those who are ill. We
will also hear some disturbing news about the White House and
the Bush administration's efforts to corrupt EPA's toxic
chemical risk assessment process. By placing politics before
science, the Bush administration is putting the public in
harm's way, this according to the GAO and EPA scientists.
A close look at the EPA's toxic chemical policies makes
clear that improvement is necessary if we are to ensure that
dangerous chemicals are properly regulated. EPA regulates toxic
chemicals in the environment under several laws. The overall
toxic chemicals law, the Toxic Substances Control Act, or TSCA,
was adopted in 1976 and was supposed to help assure that toxic
chemicals would be restricted or banned if they were hazardous.
But in essence, TSCA puts the burden on the Government to
prove a toxic chemical is a risk. That is unlike the European
program, called REACH. REACH puts the burden on the chemical
industry, where it should be, to show that chemicals are safe.
In implementing TSCA and other laws like the Clean Air Act,
the Safe Drinking Water Act and Superfund, EPA relies on risk
assessments which evaluate how toxic a chemical is and to what
extent people are exposed to it. In 1985, EPA developed a
system called the Integrated Risk Information System, or IRIS,
which establishes safe levels for toxic chemicals. The levels
set in IRIS are used as the scientific foundation for most EPA
regulatory programs and for many State programs to establish
health standards for air and water pollution, waste cleanup and
other programs. For example, the levels set for arsenic in our
water and benzene in our air went through the IRIS system.
Early in the Bush administration, the White House insisted
on changing EPA does risk assessments. What they did is, they
wanted to bring OMB, the Office of Management and Budget, and
other agencies more directly into the process. Soon after EPA
Administrator Johnson took over the agency in May 2005, he made
changing IRIS and risk assessment a high priority. The GAO
report I am releasing today criticizes the Bush administration
changes to the risk assessment process and makes it clear that
the danger faced by the public, when political interference and
influence of polluters is paramount, is serious.
Under EPA's new approach, politics can be and already has
been injected into multiple stages in the process. Now, no one
can explain to me where there is room for politics when you are
looking at the health and safety of the American people. Even
worse, the new procedure effectively requires the White House,
the Department of Defense, which contracts out much of its
weapons programs, to agree with EPA on any risk assessment
before it goes forward and before it is made public. So instead
of having the scientists at EPA decide what is good for our
health, we now have contractors essentially at the table. And
we have the private sector and those with the special interests
effectively at the table.
What makes it worse is, the entire process is kept secret,
which GAO and EPA scientists say undermines the credibility of
EPA's scientific assessments. That is because EPA scientists
are being pushed aside by White House operatives and polluters.
According to the GAO, the EPA's flawed risk assessment process
essentially derailed the risk assessment for TCE, a solvent
that is the most common organic groundwater contaminant in the
U.S. TCE causes cancer, including childhood cancer, and birth
defects. EPA's assessment for naphthalene, a component of jet
fuel that the National Toxicology Program has found ``can
reasonably be anticipated to be a human carcinogen'' has also
been derailed. Naphthalene contaminates at least 654 Superfund
National Priority List sites and many DOD facilities. GAO found
that ``DOD could face extensive cleanup costs'' if naphthalene
is more strictly controlled.
And here is the irony for me. This Administration has no
end in sight for funding of the Department of Defense. And the
Department of Defense protects us all over the world. Isn't it
ironic, while they are doing that, they are derailing defenses
against toxic chemicals? To me, it is the ultimate irony.
Similarly, GAO found extraordinary delays in the risk
assessment process for formaldehyde--you have heard of
formaldehyde--a chemical in plywood and many consumer products
that has been linked to leukemia and other cancers. An EPA
scientist with extensive knowledge of this program told our
Committee staff that the Bush administration's risk assessment
process could have ``a significant impact on public health by
delaying decisions so exposures can continue unabated to
carcinogens, chemicals that cause birth defects and
developmental effects, neurotoxic effects,
[so] a lot of people are affected.''
This isn't about affecting a few people. This is about
affecting our people in a broad way. And how many of us have
said, children are our future?
This scientist also reported to us that ``de facto, EPA
can't go forward'' without White House, DOD and other agency
sign-off. The process has, according to this knowledgeable
expert, put the scientists aside and has been ``taken over by
the White House,'' his words.
EPA's mission is to protect public health and our
environment. Politics must never play a role when it comes to
protecting our families. But as GAO has found, the series of
delays has ``limited EPA's ability to conduct its mission,''
and that is a direct quote from the GAO report.
The role of independent scientists at EPA must be restored
so that EPA can carry out its mission without secret
interference. We must also strengthen our toxics laws to ensure
that chemical companies are responsible for proving that their
products are safe, including safe for pregnant women, children,
the elderly and others who are most vulnerable to toxic
chemicals.
I so look forward to this hearing and hearing from our
witnesses on this critical topic. And if you could give Senator
Inhofe seven and a half minutes, please.
OPENING STATEMENT OF HON. JAMES M. INHOFE,
U.S. SENATOR FROM THE STATE OF OKLAHOMA
Senator Inhofe. Thank you, Madam Chairman. I don't need
seven and a half minutes. I regret that I won't be able to stay
here for the whole hearing.
Today's hearing concerns me for several reasons. First, it
was called to take a look at EPA's chemical program under TSCA,
at least that is what we were told and I think that is what the
EPA was told. However, it now appears that a major part of the
focus is on the changes in the IRIS program. Unfortunately, the
witness whom the Chairman invited from the EPA, Assistant
Administrator Gulliford, who runs the TSCA program, Assistant
Administrator Gray runs the IRIS program. So Mr. Gulliford,
while you might be able to offer some general comments on the
IRIS program, you should not be expected to be the expert that
you are in your own field.
Next, my staff was repeatedly told by the majority staff
that GAO was working on an IRIS report, but they weren't sure
if it would be ready in time. This report, in keeping with our
Committee rules, was distributed on Friday. However, we now
understand that not only was the report completed by March 7th,
but it was Senator Boxer's office that requested that the GAO
embargo the report for 30 days. While this is occasionally
done, Senator Boxer's deputy staff director went even further
to request that the embargo be extended until this hearing.
This is not a common practice and I have a letter from the GAO
that I would like to enter into the record at this time.
Senator Boxer. Without objection, so ordered.
[The referenced material follows:]
[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
Senator Inhofe. My concern in all this, inviting the wrong
EPA witness, withholding from the minority the GAO report for
more than 50 days, is that this hearing today appears to be set
up as a ``gotcha'' hearing to try to embarrass the
Administration, instead of a legitimate oversight hearing. If
the Chairman were truly concerned about oversight and changing
policy, then she would have shared the report when it became
available over a month and a half ago, and she would have
invited the correct EPA witness. I understand at one point she
wanted the Administrator, but she invited the TSCA Assistant
Administrator.
Oversight works best when it is done in the open. By not
disclosing the true intent of today's hearings to the agency
and the minority, we are left with, at best, an incomplete and
inconclusive attempt at oversight.
I believe we need to work together on oversight, such as a
hearing examining the ethanol program. This Committee has not
held such a hearing, despite massive changes in the law last
year, which has increased food prices contributing to riots.
And by the way, I would like to make that as an official
request. I am going to be on the floor today, Madam Chairman,
at some length, talking about the mandates, the ethanol
mandates and how they relate to the cost of food stocks. In
fact, this is an area where I will be in concert with what
normally are not my best friends on the environmental issues.
It is something I think you agree with, that I think we need to
determine, be concerned about this diversion of these to fuel
from food.
So I would like to make that request, I think we should
have that. I will be more elaborate on the floor in talking
about this, I have about a 1-hour speech on the ethanol mandate
and how much that is hurting a lot of people.
Thank you, Madam Chairman.
[The prepared statement of Senator Inhofe follows:]
Statement of Hon. James Inhofe, U.S. Senator
from the State of Oklahoma
Good morning. Today's hearing is to examine the adequacy of
the mechanisms for the evaluation and regulation of chemicals
by the EPA. The subject is important because the chemical
industry is a crucial part of the US economy and we have to be
mindful of what we put at risk if we over-regulate this
industry and stifle its 30 year history of innovation.
Here are some statistics. The United States is the No. 1
chemical producer in the world, generating $635 billion a year
and putting more than 5 million people to work. The US chemical
industry paid more than $27.8 billion in Federal, State and
local income taxes in 2006. More than 96 percent of all
manufactured goods are directly touched by chemistry.
But it is about more than money. Chemicals are the
essential building blocks of products that safely and
effectively prevent, treat and cure disease; ensure the safest
and most abundant food supply in the world; purify our drinking
water and put out fires. They are the foundation for life-
saving medical devices, such as sutures, internal tubing, and
scalpels. Innovations in chemistry have made planes, fighter
jets, and space shuttles safer and more secure. Plastics are
used to make lighter, yet stronger, cars and silica is an
ingredient in low-rolling resistance tires, all of which
increases automobile fuel efficiency. Alternative sources of
energy, on which cap and trade proponents are relying, are
dependent on chemicals. Wind power blades contain polyester and
resin additives and solar power relies on silicon-based
materials. Finally, chemicals keep our children and our men and
women in uniform safe by increasing the effectiveness of child
safety seats, bicycle helmets, and Kevlar vests. I could go on
and on.
The reason I point all this out is that there are many
people who come to this hearing with a belief that the US
chemicals management program is broken and that Congress needs
to completely rewrite the Toxic Substance Control Act
(pronounced TOS-KA). I do not agree.
For nearly 30 years, chemical products have been among the
most thoroughly evaluated and regulated, covered by more than a
dozen Federal laws, including TSCA. These statutes call for
regulation of chemicals based on risk. I do not believe
American chemicals innovation should be stifled by government
regulation without the clear identification of risk. We need to
ensure that we regulate chemicals based on demonstrated risk
not the just the perception or assumption of it. That
``precautionary'' concept is one that I cannot support.
There are also those who have expressed concern over EPA's
risk assessment practices. I am one of them. I have long been
concerned about the lack of transparency and participation
inherent in EPA's risk assessment process, as well as how risk
is communicated to the public. I was pleased with EPA's recent
changes to the Integrated Risk Information System. These
changes allow the public to be involved in the risk assessment
process sooner. Now, environmental groups, scientists and the
regulated community can provide data, research and comments on
risk assessments before they are finalized. Additionally, there
is now a concerted outreach effort to members of the scientific
community and more rigorous peer review. I understand that
there are those on this committee who believe this is somehow
stifling EPA scientists or putting politics into the scientific
process. But I don't understand how someone can stand up and
say they support public right-to-know, scientific community
participation and transparency when the Agency makes regulatory
decisions but not support those very same principles when it
comes to risk assessment. More science means better decisions;
more defensible decisions.
As I said 2 years ago during a toxics oversight hearing I
held when I was Chairman, there is no shortage of strong
feelings when it comes to chemicals and how they are regulated
and managed. I look forward to hearing from our witnesses today
and perhaps we will continue to uncover implementation problems
that this committee, exercising its oversight, can encourage
the Agency to rectify.
Senator Boxer. Thank you.
I am going to just use the privilege of the Chair just to
respond to say that I don't mind your attacking me on this. We
certainly did tell your staff that IRIS was a very important
part. The reason, we really wanted Administrator Johnson here,
because we think the buck stops there. But we also believe that
TSCA and the role of TSCA is very important, even though the
law has been weakened. This is bigger than just the IRIS
program. It really is about all of our laws that rely upon risk
assessment. But I don't mind that you are unhappy with me. This
is certainly not going to be the last time.
Senator Inhofe. Oh, I am not unhappy with you, if you would
me respond.
Senator Boxer. It is not the first and it won't be the
last. But I just want to say this. For me, the most important
thing, and I am sure it is for you, is not getting into an
argument about the date of the GAO report and all that. We
obviously wanted to understand it, read it and do the rest. But
it was the report we had asked for.
But what is important is the bottom line here, which is
that we are being told, and this is a scandal, frankly, that
our families are being put at risk because politics has entered
the process of these risk assessments. And this is too
important for us to bicker over how many days we told you this,
that or the other.
But I am happy to hold another hearing on this, and you
would have every right to call whomever you want, and I would
be delighted to do that at any time. But I really do want to
thank you for being here, I know you have a hectic schedule.
Senator Inhofe. Let me clarify, I certainly did not attack
you, nor would I attack you, nor will I. But on this, I think
if we do ask for am embargo, which can be very appropriate if
we share that with each other, it would be a better idea.
Senator Boxer. Yes, as you say, it has been done before,
and I will.
All right. Senator Lautenberg.
OPENING STATEMENT OF HON. FRANK LAUTENBERG,
U.S. SENATOR FROM THE STATE OF NEW JERSEY
Senator Lautenberg. Thank you, Madam Chairman. How nice it
is to start off this spring day with a discussion of not the
issues but the format or the process. And I think that if one
attempts to hide information, the biggest obfuscation took
place when we said that global warming is a hoax. And that
tried to hide the effects and the seriousness of what that
condition was ultimately is now, in front of our eyes, almost
daily on TV and news, news delivery systems.
So this is the kettle and the pot being called black. And
Madam Chairman, I know you don't need it, but stay strong on
these things. Don't let yourself be cowed.
Senator Boxer. I make you that commitment.
[Laughter.]
Senator Lautenberg. Earlier this month we held a hearing on
a matter that is still on many Americans' minds, the impact of
contaminants in our Nation's water supply and the health
hazards that they may pose to our residents. These contaminants
include chemicals that are used in rocket fuel, gasoline
additives proven to have negative effects on people's health.
The real problem with our water supply is the lack of
regulation by EPA. When it comes to regulating the industrial
chemicals that are used in thousands of everyday products, from
plastics to children's toys, the EPA is missing in action. The
absence of EPA regulation is putting people at risk.
For instance, scientific studies show a potential link
between a chemical called Bisphenol-A, which is used to make
baby bottles and water bottles and a host of medical problems,
including cancer and reproductive issues arise. But here is the
worst part. While the chemical is being developed and then used
in the products we rely on, the EPA did nothing. Instead of
speaking out for our health, they were silent. And the agency
was not just silent about this single chemical. Out of the
80,000 chemicals used now to produce the products they have
found throughout our homes, the EPA has only tested 200. It is
unacceptable.
I refuse to let my grandchildren become the newer version
of the canary in the coal mine when it comes to determining
which chemicals are safe and which are not. We need to change
the system so instead of passively waiting for a chemical to
hurt somebody, we prove that it is safe before it gets into the
hands of the consumer.
That is why I will soon introduce an updated version of the
Kids Safe Chemical Act. Chairman Boxer supported this critical
bill when we introduced it during the last Congress, and I hope
we are going to be able to work together on it again this year.
This legislation would direct the EPA to make sure that every
chemical in every product is safe before it winds up in the
hands of the consumer.
We already regulate pesticides and pharmaceuticals this
way. It seems to me just common sense that we do the same thing
for industrial chemicals that are used in everyday consumer
products. I believe that it is, and I believe that the American
public will agree. I look forward to working common sense back
into our environmental laws to make sure the products we rely
on every day are safe.
Madam Chairman, as we approach the spring and we think
about when it was that Rachel Carson started the anti-pollution
movement, it was 1963, and it was the book called Silent
Spring. It produced an anxiety, produced a tension to what we
were doing to ourselves, particularly at that time with DDT. It
took 9 years for that material to be obliterated from use and
its presence.
So this is the place and this is the time, Madam Chairman,
that we have to get on with these things, stop talking about
them and do something about them. Thank you very much.
Senator Boxer. Thank you very much. And Senator, I would be
very honored to be the lead co-sponsor on your legislation,
because I think it gets to the heart of the matter.
Senator Barrasso.
OPENING STATEMENT OF HON. JOHN BARRASSO,
U.S. SENATOR FROM THE STATE OF WYOMING
Senator Barrasso. Thank you very much, Madam Chairman.
Madam Chairman, we do need to protect our children, no
matter what age, from the effects of harmful chemicals. I doubt
there is anyone in this entire room today who wouldn't support
that goal. There is nothing we wouldn't provide for our
children. Children need safe drinking water, life-saving
medicines and safe food to eat.
One question we might ask ourselves in this hearing is the
following: has the chemistry industry and the EPA, under the
Toxic Substance Control Act, helped improve the lives and the
health of our children? To answer that, I would like to
highlight an article that ran on Thursday in the Washington
Post, a front page article, and the story is entitled For
Children, a Better Beginning: Study Finds Progress on an Array
of Issues from Birth to Age Ten.
In brief, the article says, in a wide-ranging look at how
children have fared in their first decade of life, there is a
promising picture of American childhood. Sixth graders feel
safer at school. Reading and math scores are up for 9 year
olds. More preschoolers are vaccinated. Fewer are poisoned by
lead.
The analysis, which created a composite index of more than
25 key national indicators, reports an almost 10 percent boost
in children's well-being from 1994 through 2006. It goes on to
say that, for example, the mortality rates for children ages
one to four has declined by a third. With lead, the study
reported a striking decline in the percentage of children
younger than six who have elevated lead levels in their blood.
The article mentions possible reasons for this trend, that is
improved health and conditions, better Medicare care, better
nutrition, mandatory use of seat belts, safer playground
equipment.
What role has the chemical industry played in providing
better medical care, car seats and safer playground equipment
and so on? I think there is a role. Chemistry, using chlorine,
plays a role in producing 93 percent of the top-selling
medications in the United States. Children benefit from some of
these drugs, including those that treat epilepsy, asthma and
depression. The antibiotic Vancomycin, with which I am very
familiar, which is made with chlorine chemistry, has saved the
lives of patients suffering from serious, stubborn bacterial
infections.
Chemicals make prosthetic devices used as polyvinyl
chloride, or PVC, which is a common chlorine-containing plastic
used to construct prosthetic legs and arms for children who
lose their limbs or have birth defects. Thanks to these
devices, many of these children can lead normal lives and
participate in most activities.
PVC is used to make blood bags, IV fluid bags and tubing to
deliver needed care to young patients. Incubators for
prematurely born infants are constructed of these same
plastics. The chemical industry also makes the plastics used to
manufacture child car seats, safer playground equipment.
That is not to say that it is a completely rosy scenario
for today's children. There are still areas of concern, such as
increased rates of childhood obesity and also low birthweight
babies. So we must be ever-vigilant. We need a strong and
viable regulatory framework, the same framework under TSCA that
has spurred advancements to help our children, not gotten in
the way of it. This framework can provide the next series of
advancements that can make the future better for all Americans.
We must not enact policies that hamstring new chemical
development that would prevent these new advancements.
Otherwise that next child vaccine, the next bike helmet, the
next prosthetic leg, will not be there if our families need it
the most.
TSCA has helped establish EPA as a leader around the globe
in developing the tools we need to understand chemicals. It is
a flexible statute that allows the EPA the ability to vary its
assessments of new chemicals, according to the attributes and
the expected uses of each substance. The framework ensures that
the majority of new chemical substances pose little to no risk
to our health or to the environment. Every chemical at a
certain exposure is toxic. Fluoride used in toothpaste and
purposely put into our drinking water, if ingested in massive
amounts, can cause harmful health effects. As they say, the
dose makes the poison.
My point is that we don't need to scare folks about risks
that are not there or of a low probability. That is why we need
a statute that realizes the differences between risk of
exposure and toxicity. Is TSCA perfect? No. Could there be room
for improvement? Perhaps. Could the implementation of the
current Act be improved? Absolutely.
GAO released a report in 1997 that made recommendations for
improvements. Many of these need to be implemented, in
particular, recommendations for improving the use of
confidential business information, prioritization of chemicals
for risk evaluation, reducing some of TSCA's administrative
burdens relating to chemical testing requirements and improving
and validating the models EPA uses to assess and predict the
hazards of chemicals.
With that, Madam Chairman, I welcome the witnesses and look
forward to the testimony. Thank you, Madam Chairman.
Senator Boxer. Thank you.
I just would like to put in the record, without objection,
a list of toxic chemicals that have been regulated under the
IRIS program. That is why our kids, that is certainly a strong
reason why we are seeing some good news on our kids. But what
the White House is trying to do is change it, is bring politics
into it. So we had, for example, under IRIS, we have had
regulations about arsenic, mercury, cyanide, toluene,
chlordane, DDT, PCBs, it goes on and on, many chemicals with
very long names.
The bottom line is, the purpose of this hearing is, we
don't want to go backward. Some of us want to make it even
stronger, not to hamstring our companies from making
prosthetics, I don't know where that comes into it, to be
honest with you. We are talking about protective standards in
our water, in our air, not in prosthetics. So let's not raise
false issues.
So let me just be clear about what today is about. What we
have learned is that this program that has in fact made our
kids safer is in jeopardy. As a matter of fact, the
Administration claims under their new way of doing things,
which they are now institutionalizing or trying to, that they
would take care of 50 chemicals? Fifty in 1 year?
Male Speaker.
[Remarks off microphone.]
Fifty. And they did two. So that is the purpose of this
hearing.
[The referenced material was not received at the time of
print.]
Senator Barrasso. Madam Chairman, not to be argumentative--
--
Senator Boxer. You can be.
Senator Barrasso. Pardon me. The plastics that I have seen
as an orthopedic surgeon for 25 years that have been used to
build the prosthetics are advances in plastics, and they are
chemically related. That was my point.
Senator Boxer. You are right. But we are talking about
regulating these chemicals in water and air. We are not talking
about regulating them for prosthetics. We are not talking about
banning them. We are talking about regulating them, so that
kids don't breathe them, drink them, play in them on Superfund
sites and the like.
So we are talking past each other. Nothing that you said do
I object to. I am not suggesting that these be banned for
prosthetics or anything else. I am saying we need to control
these when scientists tell us they are going to cause birth
defects, they are going to cause cancer. That is what we are
talking about.
Senator Whitehouse.
OPENING STATEMENT OF HON. SHELDON WHITEHOUSE,
U.S. SENATOR FROM THE STATE OF RHODE ISLAND
Senator Whitehouse. Thank you, Madam Chair.
I just want to express my appreciation to you for holding
this hearing. I think it is an important hearing. We have north
of 80,000 chemicals to which American families are exposed,
very few of them are tested for safety. In the program that
currently exists the burden of proof is on the regulators to
show that they are unsafe, which makes the balance really in
favor of industry rather than in favor of families.
There is increasing awareness of health risks that these
chemicals can cause. Unfortunately, we are also operating in an
environment in which the Bush administration record on
environmental and public health issues gives very much the
impression of being not a part of the progress that Senator
Barrasso described, but a counter-weight to the progress that
Senator Barrasso described.
EPA itself has too often been in the way of public
protection, as we have seen, with particularly the CAFE
standards and waiver. That is the most prominent. But over and
over again there are cases, and on the occasions when the EPA
does stand up for American families who face these health
risks, then the Administration has put OMB in the role of being
sort of the Administration hit man to knock those down.
So I think there is a legitimate concern that the
procedures that the Government Accountability Office has
addressed in its report may stack the deck further against
American families who don't have the expertise to make this
kind of determination and are relying on the Government to help
provide them with a safe environment.
So I think it is a great hearing, I am glad that you have
called it and I look forward to hearing from the witnesses.
Senator Boxer. Thank you, Senator, and I appreciate your
leadership on oversight of EPA in general. You have been very
strong on that, so we thank you very much.
Senator Craig.
OPENING STATEMENT OF HON. LARRY CRAIG,
U.S. SENATOR FROM THE STATE OF IDAHO
Senator Craig. Thank you, Madam Chair.
Well, I am sitting here listening trying to determine
whether this is a TSCA hearing or an IRIS hearing, but I will
assume that it is the politics of chemicals. Probably that is a
broader premise to the issue at hand. If you are going to talk
about the politics of chemicals, and that is legitimate, you
also have to talk about the importance of chemicals in our
society today and what they have done for society, along with
what they have done to damage society in one form or another.
Those are all phenomenally legitimate criteria for an oversight
hearing.
And Madam Chair, I am sorry, I am going to err on the side
of a doctor today and not a politician. I am going to err on
the side of Dr. Barrasso and his statement because I think it
was overreaching in the broad sense, not overreaching, but it
reaches out in the broad sense to talk about striking balance
and assuring quality human health in our Country.
Our history is replete with the lack of knowledge and
understanding as to the application of or the pollution of
chemicals into our environment. And when we found it out, when
we knew it, we began to move. From the very loud cry of Silent
Spring, as one Senator mentioned, to what we have done
effectively with TSCA, which is today a responsible model of
public policy that works and brings about that kind of balance.
My great fear is not unlike what we are experiencing today
in the petrochemical industry. When we didn't do it they did
it, meaning somebody outside our Country. And now we are being
victimized because we weren't smart enough to continue
production in our Country and do it in a clean and responsible
and environmentally sensible way.
How many times this year has our society been warned about
a product coming in from outside our Country that might in some
way injure human health? The more we regulate in ways that are
punitive, that deny a reasonable entry into the market based on
sound science, the more someone else is going to do it
offshore. The beauty of what our Country has always done
historically is its phenomenal transparency, not just for us
and our consumer when the knowledge base was there to do so,
and a good regulatory process produces that knowledge base, but
at the same time it was transparent to the rest of the world.
TSCA's importance is directly tied to entry into
manufacturing, processing, importing, and the use and
distribution in commerce as it relates to how we regulate
chemicals. Let us also recognize the value of the industry
itself to the economy of our Country. It just so happens that
it is about a $635 billion industry. We represent 22 percent of
the world's economy as it relates to the chemical industry. And
we are rapidly shoving it offshore by cost of input and cost of
regulation. That shouldn't happen. We ought to continue to lead
in that area, and we are not talking about just minor jobs, we
are talking about jobs in the industry that average $50,000 and
above, a very important industry to our Country.
So fair and balanced oversight, absolutely, Madam Chairman.
Political forum, shouldn't necessarily be that, although I am
not so surprised that it has become that. Our job is oversight
to see whether TSCA is working, whether IRIS is working. If it
isn't, then we ought to make it work. More importantly, we
ought to make it work in concert with what the rest of the
world is doing to make sure we do it better, more cost-
effective, at the same time with a sensitivity to human health
that is paramount.
It is kind of like where we are today, Madam Chair, with
energy. If it isn't clean and if it is an emitting source, we
don't want it any more. We are driving our energy economy into
cleanliness. We ought to do the same thing with the
petrochemical industry. And that isn't run them offshore,
invite them to stay in a criteria of public policy that allows
them to prosper and provide safe products for the consumer.
That is our job. We can make it as political as we want to or
we can be reasonable and responsible. I would guess the public
in the large would want us to be the latter instead of the
former.
I thank you and look forward to the testimony.
Senator Boxer. Thank you. I feel compelled to respond,
since my name was invoked, Madam Chairman, several times.
No. 1, it is not our job to keep the chemical companies at
the table. It might be in another committee. This is the
Environment and Public Works Committee. The EPA has a job to
protect public health. When it comes to the profitability of
the chemical companies, let's take that up in the Commerce
Committee. Let's look at that. Yes, but not as a criteria here.
Our job is very straightforward, and that is protect our people
from harm, from chemicals, toxics. And if we hadn't been doing
it, all those statistics that Dr. Barrasso, if I might say, has
cited, wouldn't be there.
Now, you have taken your stand with Dr. Barrasso. Now, he
is an orthopedic surgeon and I am really honored to have him on
this Committee. On the panel today, we will have a pediatrician
and we will have an Ob-Gyn. In EPA, we have many scientists
whose job it is to protect the public. So while we all need to
be listened to, I have other credentials. I am a grandma, I
bring those proudly to the table.
But the fact of the matter is, the people who know about
this are the people who are experts in toxic, are the people
who see pregnant women, who are warning them about the toxic
chemicals that are unfortunately ever-present.
I also want to make one last point here, which I think is
important. There seems to be all this ``confusion'' about this
hearing. Let me tell you the title of this hearing today, no
confusion, ``Oversight on EPA Toxic Chemical Policies.''
Policies. That means anything and everything is on the table.
We can look at IRIS, we can look at TSCA.
But politics shouldn't be played when it comes to
protecting the health of our families. That is one of the
reasons we have this hearing today, because politics is being
played when you have the White House suddenly turning its back
on the science and the EPA and inviting to the table, through
various agencies, the special interests. That is not what
should be happening when it comes to protecting the health of
the people.
And I am a little stunned that my colleagues on the other
side of the aisle aren't working with us on this, because you
love your kids and grandkids as much as I love mine, and you
would throw yourself in front of a truck for them. Well, we may
have to throw ourselves in front of a train for them here,
because there is a train leaving the station with Administrator
Johnson on it and President Bush's OMB on it, trying to derail
a very important risk assessment program that has at least done
something good to keep our children safe. If this is going to
go forward unchallenged, we are going to see a slowdown and a
delay. And everyone says that, including the GAO. We are
harming our children.
Senator Barrasso. Madam Chairman, since my name came up----
Senator Boxer. Well, we are not going to start that, but I
will go back to you after we, for the first round of questions.
Senator Klobuchar.
Senator Klobuchar. Thank you very much, Chairman Boxer.
Thank you for holding this hearing.
Just listening to Senator Craig, I just view our role as
one of oversight, that is correct. But it is also oversight of
enforcement. I come at this not only as a mother who, when you
think first hand of these baby bottles and things like that
could have toxic chemicals in it, it just hits you hard, but
also as a prosecutor. I have always learned you can have strong
laws and politicians can stand up and make credits about laws.
But if you don't have the enforcement angle and you don't have
people watching over to make sure that these laws are being
enforced, then we are not doing our job and Congress has to
come in. I believe that is what we are trying to do, is to
figure out what is going on here.
I come at this not naively but as someone that looks at
this, look what happened with these toys. Who would have ever
thought, and I don't think anyone would believe that people
want to allow AquaDots to morph into date rape drugs in this
Country, and that is what happened here. That is what happened.
They weren't, our Country, our Consumer Products Safety
Commission, wasn't watching over these toys and they came into
our Country, and they shouldn't have. And this happened again
and again and again, and finally Congress had to step in, when
the Administration did not, and say, we need more tools, what
do you need to enforce these laws, we will help you. What do
you need? A better statute on the book? We will help you. And
that is what happened in the last year in this Congress.
So it doesn't surprise me at all that we might have to get
involved in these toxic chemicals. And I was shocked to read in
this hearing the testimony of Ms. Annette Gellert, who is going
to be testifying on the second panel, and I am not going to be
able to be there for that, because have a Commerce hearing on
the mortgage crisis going on at the same time. But I read about
how she had blood tests done on herself and her daughter, and
out of 70 toxic chemicals they tested for, they found 36 in the
mother and 34 in the daughter. You figure as a mother that you
are supposed to be able to provide your child with a safe
environment and you do your best, and then you find that things
outside of your control are coming into your home.
I figure that in a Country with as many resources as ours,
there is no reason that people should have to get their safety
information from news stories or from people that are already
sick in the hospital. That holds true not just for the EPA, but
across all Government agencies, whether we are talking about
the spinach weed, the pet food that we get or the drain at the
community pool. These are all things that have gone on in this
Country in the past year.
So I am looking forward to hearing from our witnesses, Mr.
Stephenson from the GAO, about how the Toxic Substance Control
Act is being controlled, where the weaknesses have been and
what we can do better to give Americans the sense of safety
that they deserve. Thank you very much.
Senator Boxer. Thank you, Senator.
So we will start our panel first with James Gulliford,
Assistant Administrator, Office of Prevention, Pesticides, and
Toxic Substances, to be followed by Mr. John Stephenson,
Director, Natural Resources and Environment, from the General
Accounting Office, who did this report.
Mr. Gulliford.
STATEMENT OF THE HON. JAMES GULLIFORD, ASSISTANT ADMINISTRATOR
FOR PREVENTION, PESTICIDES AND TOXIC SUBSTANCES, U.S.
ENVIRONMENTAL PROTECTION AGENCY
Mr. Gulliford. Good morning. I appreciate the opportunity
to share with the Committee our progress to date as well as new
efforts underway to protect human health and the environment
from the adverse effects of chemicals as authorized under the
Toxic Substances Control Act. TSCA provides EPA with the
authority to review and manage risks from new chemicals and to
collect health and safety data as well as production, use, and
exposure information on industrial chemicals.
We use sophisticated models to assess chemicals, we
facilitate pollution prevention and we implement voluntary
programs to support our regulatory framework. We work closely
with the domestic and international community. As an example,
we have collected health and safety data on 2,200 high
production volume chemicals which cover more than 93 percent of
the organic chemical production volume. EPA has also
successfully used TSCA to bring about the phase-out or
significantly reduce the production, use or release of various
chemicals, including PFOS, PFOA and other priority chemicals.
There are many more accomplishments detailed further in the
written testimony I have submitted.
Overall, while no law is perfect, TSCA provides broad
authority for the agency to adequately control new and existing
chemicals and to address emerging chemical issues as they
arise. As I said, while there are real accomplishments, we know
there is more to be done. So this past August, the countries of
North America came together to accelerate and strengthen the
management of chemicals in North America. This new effort we
now refer to as ChAMP, the Chemical Assessment and Management
Program.
We believe these efforts will significantly improve what we
know about industrial chemicals, and will allow the Agency to
pursue necessary protective actions or mitigation if needed. We
have committed, by 2012, to complete initial assessments and
initiate needed actions on over 6,700 high production and
moderate production volume chemicals. This builds on the work
that EPA has done under the HPV challenge program, to obtain
and assess screening level hazard and environmental fate
information and use this new information reported under the
TSCA inventory update regulations.
To meet these commitments, EPA is developing risk-based
prioritizations for HPV chemicals based on hazard, exposure and
risk screening characterizations. For the moderate production
volume chemicals, we will rely on available data, Canada's work
on chemical categorization and EPA's expertise in structural
relationship analysis to prepare initial assessments. There is
a down payment on these commitments. We have already posted
hazard characterizations on 238 chemicals and in March, posted
an initial set of risk-based prioritizations for 19 chemicals.
These characterizations, which we make available on our
website, provide important scientific information and analysis
on hazards, exposure and risks, and position us to take any
needed follow up actions. The 2012 commitment for completing
the North American assessment work also sets up opportunities
for cooperation with the European Union, given the timing of
the REACH registration schedule, which extends from 2010
through 2018.
To foster cooperation, we have regular consultations with
officials from the European Commission and OECD countries. It
is vitally important to invest in this cooperation, to leverage
work, avoid duplication and improve the protection of public
health and the environment, both at home and abroad.
While we support the health and environmental goals of
REACH, we believe that effective protection can be obtained
through a more targeted and strategic approach to chemical
assessment and management under our ChAMP efforts. In addition
to the above commitments, where work is already underway, we
are asking for feedback on potential enhancements to the ChAMP
program, which combined with our 2012 commitments would provide
the most comprehensive approach to dealing with chemicals that
has ever been developed by the Environmental Protection Agency.
The first enhancement involves developing a program similar
to the HPV challenge, but for inorganic HPV chemicals. The
second enhancement under consideration would reset the TSCA
inventory to better reflect the chemicals actually made,
imported and used in the U.S. We have begun an extensive effort
to invite input from a wide range of stakeholders.
I would like the Committee to know that the IRIS process
that has been discussed today and the revisions to the process
are managed by Dr. George Gray, the Assistant Administrator of
EPA's Office of Research and Development. It is my
understanding that ORD senior staff have already briefed the
Committee on this effort.
Of course, the TSCA program does utilize the IRIS data base
as a resource for reviewing chemicals, like our efforts under
ChAMP. We work directly with ORD on a handful of assessments
that are of particular relevance to us, like PFOS and PFOA.
Again, while the IRIS data base provides my office with useful
input, ORD is the lead for the overall process, and they would
be best able to respond to questions on the recently announced
process revisions.
I am pleased to be here to share with you the highlights of
our chemicals work. We remain appreciative of the ongoing
interest of this Committee in TSCA and our new efforts under
ChAMP. I believe that TSCA provides EPA with the statutory
tools necessary to protect public health and the environment,
and the agency looks forward to continuing to work closely with
members of this Committee, your staff and others from GAO.
Thank you.
[The prepared statement of Mr. Gulliford follows:]
[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
Senator Boxer. Mr. Stephenson, thank you.
STATEMENT OF JOHN B. STEPHENSON, DIRECTOR, NATURAL RESOURCES
AND ENVIRONMENT, U.S. GOVERNMENT ACCOUNTABILITY OFFICE
Mr. Stephenson. Thank you, Madam Chairman, members of the
Committee.
GAO has issued several reports on EPA's implementation of
TSCA and EPA's voluntary programs to control dangerous
chemicals. We have concluded in this work that TSCA is
outdated, cumbersome and difficult to use in controlling the
more than 80,000 chemicals currently in the inventory.
Since TSCA was enacted in 1976, EPA has used its authority
to require chemical industry testing for fewer than 200
chemicals, that is in 30 years, and has issued regulations to
limit or ban the production of only 5 chemicals or groups of
chemicals in that same time. Voluntary programs provide EPA
useful information, but they don't negate the need to overhaul
TSCA.
In comparing the U.S. approach for controlling dangerous
chemicals under TSCA to the European Union approach under the
REACH program, we note that TSCA places the burden of proof on
EPA to demonstrate that the chemical poses a risk to human
health before it can regulate its production or use, whereas in
Europe, REACH generally places the burden of proof on the
chemical industry to ensure that chemicals do not pose such
risks or that measures will be taken for handling chemicals
safely.
My written statement includes additional information from
the toxic chemical control reports we have issued over the past
couple of years, but I want to focus my comments today on our
new report concerning EPA's Integrated Risk Information System,
or IRIS, a data base that contains EPA's scientific position on
potential health effects of exposure to more than 540 toxic
chemicals. IRIS is a critical component of EPA's capacity to
support scientifically sound environmental decisions, policies
and regulations.
In summary, we found that the IRIS data base is at serious
risk of becoming obsolete, because the EPA has not been able to
routinely complete timely, credible assessments or decrease its
backlog of 70 ongoing assessments. Our report recognizes steps
EPA has taken to improve IRIS since 2000, such as increasing
funding and centralizing staff, but points out that these
efforts have been thwarted by new OMB-required interagency
reviews, the growing complexity and scope of chemical
assessments, EPA decisions to delay assessments to wait for new
research or additional uncertainty analysis on a given chemical
and the compounding effects of delays.
While EPA has prepared over 32 toxic chemical assessments
for external review in the past two fiscal years, only four
have been finalized. Comments by the National Academies on
EPA's assessment of trichloroethlyene or TCE highlight the
problem. In 1998, EPA initiated a risk assessment of TCE, a
degreasing agent used widely by the Department of Defense and
others. EPA's Science Advisory Board approved the draft risk
assessment for public comment in 2001. DOD and others raised
questions about the assessment, which led to a National
Academies review. The Academies specifically noted in its 2006
report that the risks of TCE were substantial and that
additional studies were not necessary to finalize an assessment
needed to protect public health.
Nonetheless, after more than 10 years, TCE is back at the
draft development stage. To get EPA moving, Senators Clinton,
Boxer, Lautenberg, Kerry and Dole, spurred by TCE contamination
in drinking water at Camp LeJeune, introduced a bill last
August that would require EPA to complete its risk assessment
and issue a drinking water standard in 18 months.
Our report contains eight specific recommendations to EPA
for streamlining the IRIS program, improving the transparency
and credibility of its assessments and ensuring that EPA has
the requisite independence to achieve these goals. EPA agreed
to consider our recommendations in its February comments on our
draft report. EPA released its revised IRIS assessments process
after the report on April 10th.
It is an understatement to say that we are disappointed in
EPA's response. The revised IRIS process is not improved and is
in many respects worse than the draft we reviewed. For example,
transparency is a cornerstone of sound science. And the draft
IRIS process we reviewed would have made comments from other
Federal agencies part of the public record.
However, EPA's new process expressly defines such comments
as deliberative, excluding them from the public record. This
new process will exacerbate the problems we identified in our
report and sought to address with our recommendations, all of
which were aimed at preserving the viability of this critical
data base, which is integral to the EPA's mission of protecting
the public and the environment from exposure to toxic
chemicals.
In light of the importance of the IRIS program, we believe
that Congress should consider directing EPA to suspend
implementation of its new IRIS process and develop one that is
responsive to our recommendations for a streamlined, fully, not
selectively transparent process aimed at improving the
timeliness and credibility of IRIS assessments. EPA should also
seek congressional and public input before finalizing IRIS.
Madam Chairman, that concludes the summary of my statement.
[The prepared statement of Mr. Stephenson follows:]
[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
Senator Boxer. Thank you very much.
We will do 5-minute rounds and probably have two rounds.
Mr. Gulliford, what chemicals have you banned or regulated
under TSCA that were not voluntary withdrawn or regulated by
the industry or by Congress since you took over?
Mr. Gulliford. Thank you, Madam Chair.
We regulate and take regulatory actions related to
chemicals almost daily. Every year, we receive about 1,200----
Senator Boxer. No, no, no, I----
Mr. Gulliford [continuing].--for new chemicals----
Senator Boxer. I am not asking you that. How many have you,
in your position, chemicals have you either regulated or banned
without them being withdrawn or regulated by the industry
itself or banned or regulated by Congress? Do you have that
number off the top of your head?
Mr. Gulliford. The actions that we take, our actions at
EPA, do reflect our work, which in effect has the impact of
determining whether chemicals are brought into production or
not.
Senator Boxer. I know, but I'm asking you----
Mr. Gulliford. Those are regulatory actions.
Senator Boxer [continuing].--for a specific answer. And so
you don't have it. So will you please send to me in writing the
lists and names of chemicals that under TSCA, since you took
over, have been either banned or been regulated other than
those that the industry itself decided to do or Congress took
into its own hands, which we have done. So if you could do
that, I would be really appreciative. I understand the process.
I am trying to get to what have you done in your position.
[The referenced material follows:]
Senator Boxer. Now, Mr. Stephenson, the GAO report states
``The farther removed the scientists and experts who have
prepared or peer-reviewed the assessments are from the
negotiations and decisions over assessment changes requested by
OMB and other Federal agencies, the decisions are based more on
political rather than scientific considerations.'' I think that
is important, because Senator Craig kind of accused this
Committee of playing politics. The whole point is, the GAO
report says that there is political considerations.
So how important is it to ensure that IRIS assessments are
based on solid science rather than political considerations?
Mr. Stephenson. According to the National Academies, there
are two components there is a risk assessment part and there is
the risk management part. The management part is where you
consider political input or other circumstances, you do cost
benefit analysis and decide regulatory approaches.
However, in the risk assessment process, you don't want----
Senator Boxer. That is what I am talking about.
Mr. Stephenson [continuing].--anybody but scientists
involved.
Senator Boxer. Right. That is the point.
Mr. Stephenson. That is our major problem with the lack of
transparency and the new process is that any comments that EPA
receives from either the Department of Defense, NASA or OMB
itself are withheld from the public.
Senator Boxer. That is the second question. But the first
point I want to reiterate that you made, I think it is critical
here, is that in the risk assessment part of this, it should be
pure. It should be about the health of people, is that right?
Mr. Stephenson. Absolutely.
Senator Boxer. Absolutely. OK, that is No. 1.
Now, second, the secrecy which you raised. My understanding
is, in your report you say that the comments made by these
other entities are kept secret by the White House. You find a
problem with that, I certainly find a problem with that. Why do
you think this is the case? Do you have any thoughts?
Mr. Stephenson. I think that the OMB is muddling the two
parts of the process. They are getting involved in the science
portion, the early assessment of chemicals, when they should be
getting involved in the later, what should the regulatory
approach be, what is the least burdensome approach we can do to
regulate this chemical. They should not be muddling in the
front part, in the science.
Senator Boxer. OK. Mr. Gulliford, doesn't EPA's Office of
Prevention, Pesticides and Toxic Substances rely on information
from IRIS in their work to help prevent, to help protect public
health?
Mr. Gulliford. With respect to our chemicals program, yes.
There are a number of the IRIS characterizations that are
important to us. Through our ChAMP work, we are looking at
doing well over 7,000 chemical assessments.
Senator Boxer. But I am just trying to get at the point
about IRIS here. So you do, in some cases rely on IRIS?
Mr. Gulliford. We have asked that certain chemicals be
studied under IRIS and taken through the IRIS process.
Senator Boxer. Good. That is an important point. So don't
you want to ensure that your office uses the best available
science to protect public health and not secret information
that is tainted by outside interests?
Mr. Gulliford. We do that every day. We utilize the best
science that is available----
Senator Boxer. Well, you count on IRIS, you count on the
IRIS program for certain of these, and we have been told by the
GAO, not by me or anybody else, that politics is in the
process. So when you now hear, you get your information ipso
facto, if GAO is right, and I tend to believe them, they have a
reputation for integrity and they have no axe to grind here,
you are getting tainted information. And that is a problem.
Senator Barrasso.
Senator Barrasso. Thank you very much, Madam Chairman.
Early you mentioned about my background and training as an
orthopedic surgeon. The derivative of orthopedics comes from
the Greek, and it is the word ortho, meaning straight, and
paedos, meaning child. So lots of the training I do is with
children and I have very significant concerns in those areas.
Mr. Gulliford, if I could, I mentioned earlier this
Washington Post story about all the advances in children and
kind of getting the lead out of the system. Isn't that
something EPA should take credit for?
Mr. Gulliford. EPA has worked with HUD and with other
agencies for many years on issues of lead. We are very pleased
that, for example, or the last 20 or so years ago, we have gone
from as many as 3 million children affected by elevated blood
levels to now where CDC estimates roughly 300,000. We are also
very pleased with our new lead rule, which we believe will
actively help again to prevent exposures to lead.
Senator Barrasso. When you look at exposures in terms of
assessing risk to humans, don't you really assume the worst
case scenarios in terms of an exposure and try to stay below
those numbers?
Mr. Gulliford. We look for realistic exposure estimates. We
build in safeguards to assure that we don't approach those
exposure thresholds that we believe are dangerous or
threatening.
Senator Barrasso. If we take a look at this one size fits
all approach to so many things I see happening in Washington
here, if you used that approach to every chemical under TSCA,
wouldn't you end up wasting a lot of your time on some low
priority chemicals and really deflecting from the real issues
affecting our children?
Mr. Gulliford. We absolutely would be. One of the things
that I believe is most important is that we find a way to
prioritize our work, to identify those chemicals of concern
with respect to health of children, adults, all our people and
the environment. That is why in our ChAMP program, we have
developed a prioritization process to identify those chemicals
and then follow up with industry to assure that exposure of
those chemicals does not occur either to workers or the
environment or to people that use products that are produced
from the use of those chemicals.
Senator Barrasso. So I take it then that you don't always
agree with the chemical industry, or shall I say the chemical
industry doesn't always agree with you?
Mr. Gulliford. No, absolutely not. Our work is to evaluate
the data that they give us and make independent decisions by
the agency, rather than to allow industry alone to make
decisions.
Senator Barrasso. Thank you, Madam Chairman.
Senator Boxer. Thanks. I just want to let the record show
that the lead, the progress on lead was made under the old
rules, which is what we are trying to defend here today. And
that will show, because that is one of the good things that
happened under the old way.
Senator Whitehouse.
Senator Whitehouse. Thank you, Madam Chair. I am not sure
it is part of the record, so I would just like to start by
showing Mr. Gulliford the picture of the IRIS process. I
believe we got this from EPA staff. And I just want to make
sure that this is correct.
It shows, before 2004, an IRIS process that was already
pretty----
Senator Boxer. Would you bring that over to Senator
Whitehouse and show it----
Senator Whitehouse. And then, well, hold on a second.
Senator Boxer. That is the new one. Where is the old one?
We don't have it. So show that old one, and then we will
show the new one.
Senator Whitehouse. It starts already looking pretty
complicated with 11 steps here. Then from 2004 to 2008, it
started to look more like this, it went from 11 to 15 steps----
Senator Boxer. That is the one.
Senator Whitehouse [continuing].--and became every more
complicated. And now the draft process looks like this and has
all sorts of, I can't count the number of steps and sub-steps
that it has. It just looks to the lay viewer as if this process
is getting more complicated and cumbersome.
In addition, I am concerned about the role that OMB plays
being injected into the process relatively early on. What
scientific expertise does the Office of Management and Budget
bring to the table in these discussions about risks of
chemicals?
Mr. Gulliford. Let me start with your first question and
your comment on the complexity. That board also can demonstrate
the fact that an effort is being made to be more explicit about
all of the steps and to further or better define them, as well
as perhaps adding steps. So there are a couple of things in
effect there.
OMB has scientists and economists and professionals that
work for them as well. Their role principally, though, is to
assure effective interagency review. It happens with rules, it
happens with other programs. And the agency does believe that
in the IRIS process, interagency review, opportunity for
interagency input into the process, as well as public input,
public review and finally science review as well by third party
outside scientists, all of those are important parts of the
IRIS process.
Senator Whitehouse. Should we have concern about the
private nature, the non-public nature of OMB's review? As I
understand if, it you are an American company who wants to
comment on this, on a piece, on an administrative process, a
chemical that is being put through the IRIS process, your
comments have to be public. And if you are an American advocacy
group, if you are the Heart Association or the Cancer Society
and you want to comment on it, your comments have to be public.
And if you are an American mom or citizen who wants to comment
on it, your comments have to be public.
The carve-out is for other Federal agencies. And what it
seems to create is a loophole where, if you want to influence
this process and you don't want to say it publicly, you go to a
White House, you get them to tell OMB what to do, because it is
part of the White House, and you can stick whatever comments
you want in, and it is a way to launder comments you wouldn't
make publicly through politics and into this. Isn't that a
legitimate concern?
Mr. Gulliford. That is an assumption that you are making. I
am not certain that would or wouldn't happen. I don't believe
that it would.
Senator Whitehouse. Is there anything in the process that
would prevent that from happening?
Mr. Gulliford. There is the allowance for the agency to
review mission-critical chemicals and that be a protected
process.
Senator Whitehouse. How does that keep OMB out, if OMB has
been made amenable to political----
Mr. Gulliford. You are making the assumption that OMB is
made amenable to that political process, in the Office of
Management and Budget for interagency review, as I had stated
earlier.
Senator Whitehouse. You know, one of the things we do in
American Government is we have things be transparent and above-
board so we can prevent things from happening. So it is usually
wise, when you see a system that create an avenue for that kind
of politics to happen, to press on it and try to figure out why
the system wouldn't protect itself against that. If you leave a
door open to that, I don't think it is an adequate public
protection to say, well, we can't prove that it is being used
for that purpose is because the very process keeps it private
and confidential and out of the public view, allows it to be
done behind closed doors. That doesn't seem right, does it?
Mr. Gulliford. The final products of the IRIS process are
reviewed by third party science organizations. That is the
purpose, that ultimately, when EPA has gone through the
process, EPA has heard input from the public, EPA has heard
input from agencies, EPA has heard, people have been given the
opportunity under this process to bring data, bring
information, to bring opinion to the process, ultimately it is
still, at the end of the day, it is EPA's decision. EPA makes
the determinations on those final IRIS characterizations. And
then they are split out for third party review.
So I believe it is a transparent process. It is a process
that ultimately results in a science-based result.
Senator Whitehouse. Madam Chair, my time has expired.
Senator Boxer. Yes. I thank you, Senator. I just want to
say, Mr. Gulliford, and you are a very good witness, but
Senator Whitehouse is not the one making these charges. GAO
said this thing is so secret they talked about a black box,
that this information that you say is public is never public.
It is actually in a black box, it is secret.
So when you say to Senator Whitehouse that he is not
correct, he is relying on the investigation of this process.
Mr. Gulliford. I apologize. Senator Whitehouse asked the
question, that is why----
Senator Boxer. I understand, but I just want to make sure
that we understand the GAO makes this point. It is not an
individual Senator. He is just reiterating what we now know is
the truth about the process.
Senator Craig.
Senator Craig. Thank you, Madam Chair.
Gentlemen, thank you very much for your testimony. I am
trying to understand the process, because it appears that it is
the process that is under attack today and not the outcome. I
think we are obviously concerned about transparency. We are
also very concerned about outcome.
Something that has not been mentioned, and I ask you, Mr.
Gulliford, does it fit into the process, and that is, how many
pre-manufacturing notices has the EPA received versus notices
to commence? Now, the reason this is important, when we are
talking about propriety and ownership of product and
development of product, part of the value of the ownership is
the chemistry and the formula.
But it is important to understand that as it relates to
human health and understanding. So the question then is,
because it appears that in pure transparency you get nothing
done, because someone else can steal your work product. At the
same time, you want to make sure your work product, the end
process, is safe for human consumption and association.
So the question again is, how many pre-manufacturing
notices has EPA received versus notices to commence, meaning to
commence production once the process is completed? Could you
respond to that?
Mr. Gulliford. We get about 1,200 PMNs each year.
Senator Craig. And a PMN is?
Mr. Gulliford. Pre-manufacturing notice. I am sorry.
Senator Craig. Thank you. Use common language for us, would
you please.
Mr. Gulliford. I appreciate that. Since TSCA, roughly
47,000 of those PMNs. We have added 21,000 new chemicals to the
chemical inventory, which means that during that process,
during our regulation of those notices, our evaluation of those
chemicals, our concerns for those chemistries, our interaction
with those companies, because as you say, much of that is
confidential business information. Those chemicals are either
withdrawn because, by our work with them, they have come to the
conclusion that they are not an appropriate chemical for us, or
ultimately some of them do make it through the process,
roughly, I think 21,000 since TSCA.
Senator Craig. But percentage-wise, I understand it is
around the 50 percent mark.
Mr. Gulliford. Or less.
Senator Craig. Or less. Those who are, that which is
submitted for testing and oversight, or review, through the
process, versus that which actually makes it to the market. And
often they are withdrawn, are they not?
Mr. Gulliford. That is correct.
Senator Craig. For future research to meet the compliance
standards that you say they must meet.
Mr. Gulliford. That is correct.
Senator Craig. I see. I guess my next question, because Mr.
Stephenson says we ought to stand down and review, I think I
understand you right, and reapproach IRIS differently, and in
that, you have referenced REACH. REACH, of course, is what the
European Union uses. So that is your observation.
So let me ask a question, Mr. Gulliford, has EPA examined
REACH and its thoroughness or its responsiveness? Because it is
being touted here today as something that is working or is more
transparent or is more inclusive, versus what you are doing.
And first of all, let me ask you that. I understand there are
about 30,000 chemicals that the EU will need to register. How
do you think it compares? We have already heard from Mr.
Stephenson about he thinks it compares.
Mr. Gulliford. REACH is a regulatory chemical management
scheme that is now in place in the EU. It is just now beginning
to collect the information that is required, the testing, the
data that will be developed by industry for their estimate
again is roughly 30,000 chemicals. We will see how many are
actually produced by them and submitted.
So at this point in time, they are still in the data
development and information development testing mode, and as of
yet, decisions under REACH with respect to chemicals have not
been made.
Senator Craig. So from your point of view, you don't know
that a conclusion can be drawn as to its effectiveness?
Mr. Gulliford. I think it will be. The effectiveness of
REACH will at some point in time be known and evaluated and we
will see the benefits of it.
Senator Craig. Now, I have portrayed what I think you said,
Mr. Stephenson, to be fair. Your reaction to the comment of Mr.
Gulliford.
Mr. Stephenson. If I could clarify.
Senator Craig. Please do.
Mr. Stephenson. TSCA is the regulatory approach.
Senator Craig. I understand.
Mr. Stephenson. We are talking about----
Senator Craig. Well, we are not sure what we are talking
about.
Mr. Stephenson. We are talking about standing down the
toxicity assessments under the IRIS program, which is a
forerunner of regulation. You have to determine how toxic a
chemical is, first.
Senator Craig. I understand.
Mr. Stephenson. We have other problems with TSCA in that it
is cumbersome, it requires a two to 10 year test rule in order
to get information from the chemical industry, information that
is already provided up front under REACH from the chemical
industry. So we are kind of mixing apples and oranges here.
Senator Craig. But in our observation, or excuse me, in
your observation of REACH, which is a new program in the EU to
attempt to register and to clarify the value of or the problems
with 30,000 chemicals, can you at this time assess its quality
of work and production and its time lines?
Mr. Stephenson. It is probably too soon to tell, except
that we get much more information, the Government gets much
more information from the industry with REACH than it currently
does under TSCA without heroic efforts. And it is more of a
partnership with the industry, because the industry understands
what information it must provide to the regulatory agency. The
chemical companies here that do business in Europe must
subscribe to REACH. So it is not foreign for them to handle
that regulatory framework.
Senator Craig. So in other words, is it reasonable to
assume then, in REACH, I can't condemn it yet because I don't
know about it, or we don't have a track record of its
effectiveness, where we have chemical companies----
Senator Boxer. Senator Craig, I just--I am not going to
stop you----
Senator Craig. This is the last question.
Senator Boxer. No, no, no, let me finish. I will give you
an extra 2 minutes, because I think we will have a second round
in a few minutes, so you can use your second round now.
Senator Craig. Then wouldn't it be responsible for us,
instead of throwing the baby out with the bath water, to look
at our process and REACH, once it is implemented, through the
eyes of, in part, of the chemical companies that have to deal
with both and see which one is the most effective, the most
transparent, assures proprietaries needs necessary for a
chemical industry to exist and assures human safety.
Mr. Stephenson. We are not subscribing the REACH approach.
What we have done over the last few years is look at TSCA and
talk about how it is cumbersome to use and how it needs
overhauling. We have made specific recommendations on our
legislation, our regulatory approach, on things that need to be
improved. All we are suggesting is that REACH offers a model
for front-end information from the chemical industry that we
might consider as we overhaul TSCA.
Senator Craig. Thank you. Gentlemen, thank you much.
Senator Klobuchar, if you want, I will give you 7 minutes,
that would cover your next round.
Senator Klobuchar. No, I am just fine.
Thank you to both of you. I want to follow up on some of
Senator Craig's questions with you, Administrator Gulliford,
about the European Union. What I understand, regardless of the
effectiveness in the long term, is that they are going to be
receiving a tremendous amount of information on the safety of
chemicals in the coming years under this new law, which is
REACH, which standards for Registration, Evaluation,
Authorization and Restriction of Chemical Substances. So is the
EPA going to request this information on chemical risks from
the European program to make sure that our Country has this
same up to date and current information that they are going to
have in Europe?
Mr. Gulliford. Thank you, Senator, that is a very good
question. In fact, we are working now with the EU members, with
the EU Commission to make sure that there is a portal that
allows for access of that information.
Now, having said that, we believe that it is appropriate
for us to determine through our process which chemicals we
believe are most appropriate for our work, for our follow up
actions with respect to those chemistries. We do believe that
if the REACH process follows through and generates the data
that we expect that it will, at a certain point in time,
because I said to you, we would be committing to completing our
prioritization work by the year 2012, that we will have at that
time an opportunity to select from that data that is available
through REACH. So it is possible that we will use that data.
But it is also very probable, there are those 30,000 chemicals,
there will be a lot of those that we won't find a need for that
data as well.
Senator Klobuchar. So are you going to get that data in the
next month, or when are we going to get it? We have a panel
coming up that is concerned about the health risks here. I know
we are working through with the EU, but I would think we would
want that immediately. We have good relations with them.
Mr. Gulliford. It is industry's obligation to transmit that
data to the EU between the timeframe of, I believe 2010 and
2018. So as that data is transmitted, we will know its
availability. We will also be able to again, by looking at the
work that we propose to do, not on 30,000 chemicals by on our
high production or moderate production volume chemicals,
roughly 7,000, we will have identified the chemicals that we
believe are most appropriate for action. We will be able to go
after that data if we do believe that it will be helpful to us.
Senator Klobuchar. But wouldn't you just rather get the
data ourselves than have to go through the EU? It seems to me,
just getting to Mr. Stephenson's point, that we should be, the
agency itself, which knows the most about this law, should be
pushing to update our laws so we get that information.
Mr. Gulliford. We will have access to the data when we need
it. I think it is more appropriate--it is not our interest to
be a data manager, it is to be a data user. I think the most
important thing that we can do at EPA is utilize valuable data
when we need it in a way that allows us to make effective
decisions.
Senator Klobuchar. OK. Mr. Stephenson, do you feel it is
fair to say that agency officials in Europe are going to have
access to more information on potential threats from chemicals
when their new law kicks into gear than we will have in the
United States?
Mr. Stephenson. It does under the old law, and they will
get more under the new law. There is a table in the back of one
of our TSCA reports that does a side by side comparison of what
we get under TSCA versus what we get under REACH and the
Canadian approach, for that matter.
Senator Klobuchar. And what types of information, I will go
back and look at that table, but could you give me the greatest
hits of information they are going to have?
Mr. Stephenson. It is characteristics of the chemicals, but
it is also any risk assessment data they have done, any tests
they have undertaken. They certify to all that data before it
is provided, before a chemical is approved for production.
Senator Klobuchar. Could you talk a little bit about the,
earlier you mentioned the need to update these laws, including
adequate testing of chemicals, how can we expand that authority
under TSCA, if we were to look at revamping this law?
Mr. Stephenson. Are you talking about TSCA or the risk
assessment process?
Senator Klobuchar. The risk assessment process.
Mr. Stephenson. The risk assessment process, again, TSCA is
a regulatory approach. We are concerned with the scientific
basis for the regulations that is the IRIS program. We are so
concerned about OMB involvement here that not only are the
comments from the interagency review process not given to the
public like every other piece of science input is given, but
they are actually dictating which assessments EPA can
undertake. They had them withdraw five that the Clean Air
Office wanted.
Senator Klobuchar. They had them withdraw, what was that?
Mr. Stephenson. Withdraw assessments on five chemicals that
were needed by the Office of Clean Air, because they were acute
assessments, which means short-term assessments that the Clean
Air Office needed for its Air Toxics program, for example. Mr.
Gulliford said he uses the data in IRIS and suggests studies
that were being done. Well, that is exactly what happened, the
Clean Air Office asked for these, OMB said no, they are not
important, we are not going to do those.
So it's not only the transparency in the commenting process
that is important, it is EPA's independence in controlling
which assessments they do. The scientists at EPA must have
independence.
Senator Klobuchar. And you believe that the transparency, I
believe as a child of a journalist that transparency is very
important if you want to get to the truth.
Mr. Stephenson. It is a principle of sound science.
Senator Klobuchar. Right, that kind of transparency. It is
also going to get at decisions that they make, because you
think that we want to, and Mr. Gulliford claims they are not
biased in any direction, but that if we want to get all that
information out there we have to basically open it up.
Mr. Stephenson. Right.
Senator Klobuchar. Do you have other examples of other
agencies from a GAO perspective where they are allowing for
these comments to be seen?
Mr. Stephenson. Well, in any scientific risk assessment,
ask the National Academy, ask the National Science Foundation,
any scientific body understands the importance of any research
that is offered, any comments that are made on the risk
assessment to be available to the public, so the scientific
community can look at those and decide their worth.
The fact that after that process is done, it is offered to
peer review and the public, doesn't forgive that transparency
in the earlier part of the process. So it is just a cornerstone
of sound science, and that is why we are so passionate about
this intervention in the process.
Senator Klobuchar. I appreciate it, and I also appreciate
your bringing this out to us in your own manner. I just, when I
look at the history that we have seen in this Committee with
the involvement in some of the politics in this science, I have
always appreciated how people have been willing to come forward
and tell us we could do a better job if we just had all the
information out there. I am very hopeful that will change
within the next year. Thank you.
Senator Boxer. Thank you.
Here is what we are going to do. We are going to have a
second round, and we will start with Senator Barrasso, go to
Senate Whitehouse, 2 minutes each. And I don't have any further
questions, so I will just make closing remarks.
But before Senator Klobuchar leaves, we just got word that
a Federal judge has found the Bush administration guilty of
violating the Endangered Species Act and ordered the
Administration to issue a final listing decision for the polar
bear by May 15th. The reason I bring it up is that this
Committee has been on this case for quite a while. I wanted
everyone to know that. I am pleased about that.
Senator Barrasso.
Senator Barrasso. Thank you, Madam Chair.
Mr. Gulliford, just one last question. On products that are
already on the market, when it comes to issues of safety risks
for our children, does the EPA have the appropriate authority
under TSCA to go back and require new information, promote
research, require testing on products already on the market? Do
you feel you have the authority to go do what needs to be done?
Mr. Gulliford. Yes, we do have the authority to issue test
rules, yes.
Senator Barrasso. Thank you, Madam Chairman.
Senator Boxer. Senate Whitehouse. Senator Whitehouse, I
will give you a minute of my 2 minutes, so you have three.
Senator Whitehouse. As I understand it, OMB gets involved
at the very get-go when nominations as to what drug will be
considered are first brought forward. Is that what you were
referring to, Mr. Stephenson, the early decision?
Mr. Stephenson. I don't know whether that happens
routinely, but it has happened.
Senator Whitehouse. Yes. It looks like there is room for it
right in the process to happen routinely. Then there is an OMB
interagency review which I think is what we were referring to,
Mr. Gulliford was referring to a minute ago when he said that
it was then followed by other public comments on review and
that provided for some transparency, because you couldn't see
what they said, you could at least see what change resulted.
But it looks to me like when you get down here to the
bitter end, here is OMB again with a second bite at the apple,
and from there it goes to a reviewed internal assessment that
address the OMB interagency comment to the EPA for clearance
and out without any further comment. So I don't see how it is
true, what you told me, that after the secret OMB input is
received, there is further opportunity for transparency. It
looks like that they get the last bite at the apple, don't
they?
Mr. Stephenson. Are you asking me?
Senator Whitehouse. I am asking Mr. Gulliford.
Mr. Gulliford. I am not familiar with that chart, as I
indicated, and I would have to examine it to answer that
question. I will be happy to take that question back and
provide the Committee with an answer to that.
Senator Whitehouse. OK. I would appreciate it. Mr.
Stephenson?
Mr. Stephenson. The final assessment is shared with the
public who can then look at the research, but you can't see
what happened in the steps prior to that. You can't say, the
DOD offered a new piece of research or something, you can't see
what that was. If they had a concern, you don't know what it
was. This is the scientific process.
The policymaking process is the risk management, when you
are assigning regulatory approaches. It has no business in this
part of the process. Now, OMB was saying, we are just
coordinating via Government agencies the Federal family, as
they would put it.
Senator Whitehouse. But there is nothing that you are aware
of in the process that limits them to that? I mean, if the
worst case scenario is that a polluter comes to the White
House, makes big campaign contributions, agrees to be a pioneer
or whatever it is, and says that they are going to, you know,
but they want OMB to put the word in for them through this
process, there is nothing in the process itself that would ever
disclose that or surface that or prevent that from happening.
Mr. Stephenson. We have no evidence of that happening. All
we are saying is that to have complete transparency in the
process eliminates----
Senator Whitehouse. I am not suggesting it has happened,
either. But there is nothing about this process that would
prevent that or disclose it if it happened at this point.
Mr. Stephenson. That is our fear.
Senator Whitehouse. Yes. Thank you.
Senator Boxer. Thanks, Senator.
Let me say that, to Senator Craig, who said this hearing is
just concerned about process and not outcomes, that is wrong.
The outcomes have already been a disaster, because they put
this into play without it being officially done. They have
already put this process into play.
And what has happened is, EPA itself said they should be
doing 100 chemicals, regulating over 100 in 2 years, and they
have regulated 4 chemicals. So outcome, yes. We are not seeing
the protection of the American people.
Second, I want to thank GAO from the bottom of my heart for
doing this for us. This notion that secrecy is going to be
built into this process, where the American people are the ones
who will suffer if the wrong decision is made is a complete
outrage. It goes against the spirit of this whole Country,
which is openness and trusting its citizens with information.
Third, shunting scientists aside and putting in front the
political folks is so obviously a problem that I can't believe
we are not hearing outcries from my friends on the other side
of the aisle who, when and if we do get a Democratic President,
it will be those folks in the room. No one should be in that
room in the early risk assessment stages at all except the
scientists and the people concerned about health. Mr.
Stephenson, if you made any point in a passionate way, that is
the point.
There is room for all these other folks as we debate what
to do. But in the setting of what is safe for our people, it
has to be pure, done by the people who have no axe to grind,
who simply have a concern with the science and what it means to
the health and safety of our people.
Look, when I go home I hear all the time the fears of my
constituents about what their kids are being exposed to, what
their pregnant daughters are being exposed to, what should she
eat, what should she avoid, what is the problem? I wish I could
tell them that we have had a stellar, we have done a stellar
job here. We haven't. It is a nightmare.
And I will tell you, it is already a nightmare. If this
process is put into place, it will institutionalize this
nightmare and set us up for scandal. Because Senator Whitehouse
said it as clearly as it needed to be said, people are going to
be represented around that table, and we will never know. And
Senator Whitehouse, I want you to know, as we struggle to get
e-mails back and forth on the waiver, we can't get them. And
you know what the answer is from the Bush White House? You are
not entitled to these, they are interagency comments.
So you know, we weren't born yesterday. Well, you can tell
that from looking at me, I was definitely not born yesterday
and I do understand that this is a secret process, it is a
nightmare. And I just want to thank our witnesses for making it
very clear to us that is the case. Thank you very much.
We will call up our second and final panel. Professor Linda
Giudice, who is an M.D., a Ph.D., a Chair of Obstetrics,
Gynecology and Reproductive Sciences at the University of
California, San Francisco; Annette Gellert, who is the Co-
Founder and Chair of the WELL Network; V.M. DeLisi, Fanwood

Association; Laura Plunkett, Ph.D., Integrative Biostrategies,
LLC, minority witness; Professor Lynn Goldman, she is our
pediatrician, Chair of the Program in Applied Public Health,
Johns Hopkins University, former Clinton EPA Assistant
Administrator for Pesticides and Toxic Substances.
Well, those were such long introductions you have time to
actually have a seat. So we will go forward, and we will ask
Dr. Giudice to address us on this. We will give you each 5
minutes and then we will have lots of time for questions.
STATEMENT OF LINDA C. GIUDICE, M.D., PH.D., MSC., PROFESSOR AND
CHAIR, DEPARTMENT OF OBSTETRICS, GYNECOLOGY AND REPRODUCTIVE
SCIENCES, UNIVERSITY OF CALIFORNIA, SAN FRANCISCO
Dr. Giudice. Thank you. Good morning, Chairman Boxer and
Committee members. Thank you for the opportunity to provide
testimony at this important hearing today, where I shall focus
on three things: one, disturbing trends about male and female
reproductive health and development; two, how chemicals in our
environment can affect these; and three, preserving health now
and for future generations.
During my career as a reproductive endocrinologist and
infertility specialist, I have treated thousands of patients
with infertility and reproductive disorders: young men with
abnormal sperm, teens into menopause, little girls with puberty
at 6 years old and women with endometriosis, uterine fibroids,
incapacitating pain, infertility and miscarriage. We do not
know the underlying causes for most of these disorders, but
increasing scientific evidence suggests that environmental
contaminants play a role.
Five years ago, one of my patients questioned whether her
exposure to environmental chemicals as a child growing up near
a PCB-contaminated site on the East Coast could play a role in
her infertility. For me, this was a wake-up call, because we
know that hormones can affect human development and some
environmental chemicals at like hormones.
There are disturbing trends in the United States. The
percentage of women in their peak time of fertility, less than
25 years of age, who report difficulty in conceiving and
maintaining pregnancy, has doubled from 4.3 to 8.3 percent
between 1982 to 2002. Over the past 50 years, sperm counts have
decreased by 50 percent in industrialized regions. Compared to
30 years ago, over 25 percent more women get breast cancer, 45
percent more men get testicular cancer and 76 percent get
proState cancer. Thirty percent more babies are born
prematurely, and among the most common birth defects today are
malformations of the male reproductive system.
Scientific evidence highly suggests that exposures in the
womb or in early childhood to environmental contaminants can
cause in humans some of these trends, including birth defects,
pre-term birth, low birth weight, learning disabilities,
childhood cancers and later effects as adults, diabetes,
obesity, heart disease, infertility and cancer. So adult
disorders happening because of exposures in utero.
Since World War II, nearly 90,000 chemicals have been
produced and there is ubiquitous exposure to environmental
contaminants in our air, water, food, drink, cosmetics,
personal care products, pesticides and everyday household
products. Exposure to these around the time of conception,
during pregnancy or infancy can be particularly powerful
because these are times of special vulnerability, where
important developmental changes are taking place. These
exposures can also affect subsequent generations.
For example, bisphenol A, a chemical that is in can linings
and present in nearly every one in the U.S., can have such an
effect. Dr. Pat Hunt at Washington State showed that female
fetuses of BPA-exposed pregnant mice had damaged eggs and
abnormal chromosomes. Abnormal chromosomes are a leading cause
of miscarriage, congenital defects and mental retardation in
humans. The study also showed the prenatal BPA exposure
resulted in damage across generations.
Another example is phthalates, common in personal care and
vinyl products. Exposure during pregnancy can lower fetal
testosterone, a hormone important for male reproductive tract
development. In animals, this is linked to undescended
testicles and deformed penis at birth. Dr. Shanna Swan has
shown that pregnant women with higher phthalates have a greater
risk of having little boys with decreased genital dimensions,
supporting effects on the male system in the human.
Exposure to chemicals like these interferes with proper
functioning of the endocrine system, raising concern among
health care providers and scientists, and others include
pesticides, solvents and heavy metals. So what to do?
We need to ensure that couples can conceive if they wish
and have a healthy pregnancy and healthy children and
grandchildren. We need the Federal Government to fulfill its
mission, assemble existing scientific knowledge, impartially
reviewing it in an unbiased manner following scientific
principles free of ideology. For some chemicals we have
scientific data, but for many, we do not. And the absence of
data doesn't mean that a chemical is safe, it just means that
we have no data.
For these chemicals, we need actions that require providing
sufficient information so our Government can move forward to
prevent harmful exposure and by acting now, to guarantee the
health of our children and our grandchildren and generations to
come.
My thanks go to the Society for Women's Health Research,
our UCSF Program on Reproductive Health and the Environment,
the Reproductive Health Technologies Project, and the American
Society for Reproductive Medicine, for their help in preparing
this testimony. Thank you.

[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
Responses by Hon. James Gulliford to Additional Questions
from Senator Boxer
Question 1. Dr. Giudice. please describe how sensitive the
human reproductive and other hormone controlled systems can be
to toxic chemicals during periods of particular vulnerability,
such as pregnancy or when infants are rapidly developing in the
first few years after birth?
Response. Critical and sensitive windows occur
periconceptually (prior to, during and shortly after the
fertilization of the egg) and during pregnancy; infancy,
childhood and puberty (Woodruff et al. 2008). A critical window
of susceptibility is a time-sensitive interval during
development when exposures to environmental contaminants can
disrupt or interfere with the physiology of a cell, tissue or
organ (Louis In Press; Morford et a!. 2004). It is a period
characterized by marked cellular proliferation and development
and numerous changing metabolic capabilities in the developing
organism (Calabrese 1986; Louis In Press). Exposures to
environmental contaminants during this window may result in
adverse, permanent and irreversible effects that can have
lifelong and even intergenerational impacts on health.
Researchers have suggested the need to also define sensitive
windows of susceptibility. Exposures during sensitive windows
of susceptibility may still affect development or result in
eventual adult disease, but with reduced magnitude compared to
the effect of exposure during the critical window of
susceptibility (Ben-Shlomo and Kuh 2002; Louis In Press). For
example, diethylstilbestrol (DES) exposure reprograms the
expression of estrogen responsive genes in Eker rats exposed on
post-natal days 3-5 or 10-12 (critical window of
susceptibility). leading to increased incidence of uterine
leiomyoma. In contrast, rats exposed on post-natal days 17-19
(sensitive window of susceptibility) did not experience this
developmental programming and had a rate of uterine leiomyoma
that was elevated but not statistically different from control
animals (Cook et al. 2007).
the des example
Prenatal exposure to DES, a synthetic estrogen and thus an
endocrine disrupting chemical (EDC), provides an unfortunate
example of the influence of exposure to an endocrine disrupting
compound during a critical window development. DES was given to
U.S. pregnant women between 1938 and 1971 under the erroneous
assumption that it would prevent pregnancy complications. In
fact, in utero exposure to DES alters the normal programming of
gene families, such as Hox and Wnt, that play important roles
in reproductive tract differentiation (Miller et al. 1998;
Pavlova et al. 1994; Taylor et al. 1997; Woodruff and Walker In
Press).
As a result, female offspring exposed to DES in utero are
at increased risk of clear cell adenocarcinoma of the vagina
and cervix, structural reproductive tract anomalies,
infertility and poor pregnancy outcomes, while male offspring
have an increased incidence of genital abnormalities and a
possibly increased risk of proState and testicular cancer
(Schrager and Potter 2004). These observed human effects have
been confirmed in numerous animal models which have also
provided information on the toxic mechanisms of DES. Animal
experiments have also predicted changes later found in DES-
exposed humans. such as oviductal malformations (Newbold et al.
1983), increased incidence of uterine fibroids (Baird and
Newbold 2005; Cook et al. 2005; McLachlan et al. 1980) and
second-- generational effects (Newbold et al. 1998, 2000) such
as increased menstrual irregularities (Titus-Ernstoff et al.
2006) and ovarian cancer (Blatt et al. 2003) in DES-
granddaughters and increased hypospadias in DES-grandsons
(Brouwers et a!. 2006; Klip et a!. 2002).
DES is but one example of how exposure to EDCs can disrupt
developing organ systems and cause abnormalities that only
appear much later in life or in the subsequent generation
(Colborn et al. 1996). Other examples include: prenatal
exposure to bisphenol a, an estrogenic chemical, in mice
resulted in effects on the daughters developing eggs (Susiarjo
and Hunt In Press), and prenatal exposure to phthalates, an
anti-androgenic chemical, can result in adverse effects on male
reoproductive development such as poor sperm quality and
increased incidence of cryptorchidism (undescended testis) and
hypospadias (abnormal penis development) (Woodruff et at, under
review).
Question 2. Dr. Giudice. could you please explain the
importance of considering human exposures to multiple chemicals
on very delicate biological systems. like the human endocrine
system?
Humans are exposed daily to a mixture of environmental
contaminants in air, water and food. In a recent biomonitoring
study of over 150 contaminants, the U.S. Centers for Disease
Control and Prevention (CDC) reported that all 150 chemicals
were detected in some portion of the U.S. population and that
several of the chemicals, such environmental tobacco smoke,
lead, mercury and phthalates, are detected in nearly all or all
of the population (CDC 2005). These and similar biomonitoring
efforts improve our understanding of current body burdens of
environmental contaminants. With this knowledge comes a need
for better science on the health risks associated with current
patterns of exposure, including increased risks resulting from
exposures to multiple chemicals. For example, the majority of
studies and regulatory focus have been on exposures to
individual phthalates, which may underestimate the actual
risks. Over 95 percent of the population from ages 6 and to
over 65 years is exposed to at least 5 phthalates on a regular
basis (Silva et at 2004). Certain phthalates can inhibit
testosterone synthesis, thus decreasing testosterone levels.
Reducing testosterone levels in rats during in utero
development can results in adverse effects on male reproductive
development including decreased sperm counts, decreased ano-
genital distance, hypospadias, cryptorchidism, and decreased
size or agenesis of the accessory sex glands (Woodruff et aI.,
under review). The severity of effects increases with the dose.
Recent studies show exposure to mixtures of chemicals that
can reduce testosterone levels can have dose-additive effects.
Rats exposed to a mixture of pesticides that can decrease
testosterone levels, vinclozolin, procymidone, and f1utamide,
at doses that would not have caused hypospadias alone, resulted
in over 50 percent of animals with hypospadias (Christiansen et
al. 2008). Another study found prenatal exposure to a mixture
of seven phthalates and pesticides produced cumulative, dose
additive outcomes in the androgen-dependent tissues (Rider et
al. 2008).
A study of the thyroid system has found similar results. A
study of a mixture of 18 thyroid disrupting chemicals (dioxins,
dibenzofurans and PCBs) was tested at doses comparable to human
exposure levels for effects on thyroid hormone levels in rats.
The mixture had a dose-additive effect on thyroid hormone
levels at environmentally relevant doses and a 2-3 fold greater
than dose-additive effect at higher doses (Crofton et al.
2005).
The studies show that chemicals acting on the same system
can have cumulative effects. Assessments considering single
chemicals in isolation are therefore likely to underestimate
the potential effects from real-world exposure to chemical
mixtures (Woodruff et aI., under review).
Finally. biomonitoring data indicate that more effort is
needed toward approaches that identify and mitigate exposure to
harmful chemicals prior to measuring these contaminants in
people.
Question 3. Dr. Giudice. as a public health professional
and scientist. how important is transparency in ensuring a
valid and strong scientific process?
Response. To make informed decisions. it is critical we
have the best science available to inform what we know and what
we do not know about how environmental chemicals can influence
health. Science is an iterative process, as scientific inquiry
moves forward, further insights are gained and new questions
arise. Capturing and translating the complexities of the
science is an ongoing challenge in the regulatory and policy
arena. While science pursues new areas of inquiry, decision
making requires timely answers to questions about risks and
hazards to public health in order to mitigate future or current
potential harm (Woodruff et aI., under review). Regulatory
context also requires a different sufficiency of evidence. For
example, it is not necessary to identify every mechanistic step
leading from exposure to outcome to make decisions that
consider public health. For example, regulatory decisions are
often made based on evidence that a chemical is ``likely'' to
cause a particular outcome, such as cancer. Transparency is an
important part of the scientific process--it allows full
evaluation of the methods and protocols used from which
conclusions are drawn. Without transparency, we cannot fully
evaluate the findings from studies nor the conclusions, and
this limits our ability to make informed decisions.
Question 4. Dr. Giudice. at the hearing. another witness
raised questions about some of the data you relied upon in your
testimony. Would you please elaborate on the scientific
information you relied upon in your statements. with citations
to the literature?
Response. In the beginning of my testimony, I referred to
some concerning trends in reproductive health. The sentence and
references are below: Compared to 30 years ago, over 25 percent
more women get breast cancer (NCI 2004), over 45 percent more
men get testicular cancer (Bray et al. 2006; Sokoloff et al.
2007), and 76 percent more men get proState cancer (Penson and
Chan 2007).
Senator Boxer. Thank you very much, Doctor.
Our next majority witness is Annette Gellert, Co-Founder
and Chair of WELL Network. Welcome.
STATEMENT OF ANNETTE GELLERT, CO-FOUNDER,
CHAIR, WELL NETWORK
Ms. Gellert. Good morning, Chairman Boxer, members of the
Committee. Thank you for this opportunity to testify.
My name is Annette Gellert. I am a wife and the mother of
three children. I am a Founder of the WELL Network, which
promotes green planning, a comprehensive process between
industry, government, scientists and informed citizens to solve
together environmental health problems.
I am also Chairman of Resource Renewal Institute, whose
Green Plan Center researches advanced environmental management
strategies.
After a bill was introduced in California concerning
biomonitoring, I wanted to know what potentially toxic
chemicals might be inside my family. My family and I had our
blood tested in 2006 by the Environmental Working Group to
determine possible exposure to 70 toxic chemicals. I was
alarmed to find out that I had 36 chemicals in my body and
shocked that my 16 year old daughter, Heather, had 34 chemicals
in hers. There were similar results in the rest of the family.
Heather has been on the planet for such a short time, yet she
lives in a much more toxic environment.
Of the chemicals that were found in our bodies, some have
already been restricted in the European Union. These chemicals
are suspected of being harmful to the thyroid, as well as
reproductive and neurological systems. I am worried about my
children's health. I am worried about my children's ability to
reproduce. I am worried about the health of their children, our
grandchildren. I am not alone.
I will do everything in my power to protect my children and
I am here to ask you to do the same. I am a reproductive cancer
survivor, cancer of the placenta is what I had. Too many of my
friends are fighting cancer. While I was preparing for this
hearing, I got very bad news. My husband, Fred, was diagnosed
with bladder cancer. We are going through that now.
A known cause of bladder cancer is industrial chemical
exposure. No doubt many of you in this room have similar
stories. The cancer rate keeps going up.
There is mounting evidence that numerous chemicals in our
environment are seen as contributors to illness. Some of them
are known carcinogens. When my children needed Tylenol in
school, it required my written permission. When they are
exposed to chemicals, it happens without my permission and
without my knowledge.
We come into contact with toxic chemicals all the time,
from cosmetics to electronics to cleaning agents to plastic
containers to children's toys to baby bottles and teethers. We
are exposed to harmful chemicals in every aspect of our lives.
We have had no choice in our past exposures and continue to
have little choice now.
Only a very small percentage of chemicals have been tested
for toxicity. We are in a crisis. America needs a new approach,
a proven, better way, green planning. The key to progress is
building trust that promotes cooperation between sectors,
Government, industry, science and an informed public. This
strategy is working very well in other countries, where it has
been in action for nearly 20 years, creating environmental and
economic success.
And now the EU has introduced REACH, a new integrative
chemicals policy which is already having an effect, setting the
terms for global markets and manufacturing and market access.
We are not scientists or chemists. Our concerns represent
millions of other women who fear the impact of products we use
daily. There is virtually no information we can trust on
whether products are safe or not. We need to make those
decisions by ourselves.
There is no American scientific body that has assessed all
chemicals in common use to determine their impact on human
health and no place to get that information. We are greatly
concerned that by falling behind other countries' regulations,
the United States will become the dumping ground for all the
products that cannot be sold in Europe. Because their
regulations are stricter than ours.
In the United States, we must prove harm before a product
is removed. In Europe, industry must prove safety before a
chemical is introduced. We urge you to protect us and start
this process by looking at chemicals in a comprehensive way. It
is the right thing to do.
Thank you.

Senator Boxer. Thank you so much for your moving testimony.
Mr. DeLisi, Fanwood Chemical, Inc., Synthetic Organic
Chemical Manufacturers Association, minority witness, welcome,
sir.
STATEMENT OF V.M. DeLISI, PRESIDENT,
FANWOOD CHEMICAL, INC.
Mr. DeLisi. Good morning, Chairman Boxer and distinguished
members of the Committee. My name is Jim DeLisi, I am President
of Fanwood Chemical, located in Fanwood, New Jersey, and I
might add, the proud father of two grown daughters and a
grandfather of one.
I have been employed by Fanwood Chemical for over 30 years,
and have specialized in the marketing of organic chemical
intermediates in North America as well as Europe and South
America. In addition, I have been heavily involved in trade
issues that impact our industry. I have served as chairman of
the Synthetic Organic Chemical Manufacturers Association,
better known as SOCMA's International Affairs Committee for
many years. In addition, I am the Chairman of ITAC 3, the
Industry Trade Advisory Committee for Chemicals,
Pharmaceuticals, Health Science Products and Services
administered jointly by the United States Department of
Commerce and the United States Office of the Trade
Representative.
Thank you for this opportunity to share with you my
company's perspective on current chemical risk management
regulations and initiatives by the U.S. Environmental
Protection Agency. My remarks will also address generally
significant concerns about Congress moving in the direction of
adopting over-reaching regulatory schemes, such as Europe's
Registration, Evaluation, Authority and Restrictions of
Chemicals Program, better known as REACH.
Fanwood Chemical currently has two full-time employees and
two part-time employees working from our offices in Fanwood,
New Jersey. We also have a working relationship with senior
members of our industry for help on special projects. The
products we sell are primarily used to make color or are
functional additives in lubricating fluids. In these instances,
we are responsible for bringing to the marketplace products
produced in U.S. manufacturing facilities and are backed up by
their staffs.
We are also experts in REACH and the business challenges
this program presents, with special emphasis on its impact on
non-EU based companies. This combination of activities has
required us to have a working knowledge of EPA's Toxic
Substances Control Act, the Federal Insecticide, Fungicide,
Rodenticide Act and many other EPA programs, as well as similar
programs in countries where we have direct exports. We also are
knowledgeable in programs for countries where have indirect
exports, i.e., our customers export our products to those
lands.
Fanwood Chemical was founded by my father, Vince DeLisi, in
1971. He could have very successfully completed his career in
the chemical industry without at all ever leaving the shores of
the United States. However, the primary industry we were
serving at the time was the manufacturers of dyestuffs, so I
clearly could not have had a successful career only within the
bounds of the United States. Therefore, in 1980, we began to do
business in the international arena, first into Europe. It was
a challenge then and continues to be a challenge today to sell
U.S.-produced goods internationally because of severe
competition we face from all over the world.
Since 1976, thousands of chemicals have been evaluated by
the U.S. Environmental Protection Agency under the Toxic
Substances Control Act for potential human health and
environmental effects. American chemistry has invested and
continues to invest significant resources to assure that
products we sell meet rigorous regulatory standards and do not
present an unreasonable risk to the health of the environment.
To the contrary, in fact, chemicals produced by SOCMA members
daily improve the lives of millions of Americans. These
chemicals assist the young and the elderly alike, helping the
healthy to stay well and the sick to recover. Other chemicals
produced by industry go toward defending our Nation against
terrorism, enabling American workers to perform their jobs
safely and transporting millions of travelers across our
Nation. We are also confident that chemistry will likely be the
key to solutions to minimize global warming. All of these
benefits are made possible by the appropriate balance in our
existing system of chemical control regulation and the vast
commitments of chemical industry resources to product
stewardship.
I urge this Committee to thoughtfully consider whether it
is really necessary or wise to adopt a monolithic new
regulatory regime for chemical regime like the EU's REACH,
Registration, Evaluation, Authorization and Restriction of
Chemicals, program. In our view, existing EPA regulation and
voluntary initiatives are sufficient and far more appropriate
than REACH, to control possible hazards and still preserve the
sustainability of America's third largest manufacturing
industry.
Our industry accepts our responsibility to profitably make
products that are safe under expected exposure conditions, an
obligation that EPA polices under TSCA. But Congress has also
established a policy in TSCA that chemical regulations should
not impede unduly or create unnecessary economic barriers to
technological innovation. This balance of regulatory burdens
and public benefit is crucial for small American business which
would be hit hardest by a REACH-type scheme.
A common assumption that chemical companies each employ
thousands of workers and have unlimited resources are myths.
Seventy percent of SOCMA members, many of which operate in New
Jersey, are classified as small business by the Federal
Government. Though not a manufacturer in the pure definition,
Fanwood Chemicals sells chemicals domestically and abroad to
manufacturers that produce end-use products. Manufacturers
large and small rely on companies like mine to source chemicals
on their behalf, enabling them to reliably meet American
consumers' demand for their products. In a major way, Fanwood
Chemical and the many small companies like it represent the
underpinnings of the industry. Although we are small, our
regulatory obligations are very similar----
Senator Boxer. Sir, I want you to conclude.
Mr. DeLisi. OK.
Senator Boxer. Yes.
Mr. DeLisi. We believe that an American REACH would not
only hamper innovation but reverse the progress made over the
course of many years by Federal regulators in the chemical
industry. Thank you for this opportunity to share with you
Fanwood Chemicals' perspectives on these issues.

Next is Dr. Laura Plunkett, Ph.D., Integrative
Biostrategies, LLC, a minority witness. Welcome.
STATEMENT OF LAURA M. PLUNKETT, PH.D., DABT, INTEGRATIVE
BIOSTRATEGIES, LLC
Dr. Plunkett. Good morning, Madam Chairman and Senators. I
want to thank you for the opportunity to be here today to speak
to you.
My name is Dr. Laura Plunkett. I am a pharmacologist,
toxicologist and a human health risk assessor. In my job every
day I look at these issues related to what chemicals in our
environment are affecting our health. I work for industry
sometimes, but I also work for individuals, and often give
advice to individuals or work on cases where individuals have
been harmed by chemicals or by individual consumer products. So
I can look at this from both perspectives.
My testimony today is related to the adequacy of current
risk assessment methods and regulatory programs to evaluate
chemicals and identify risks to sensitive populations in the
human population. That includes the developing fetus, infants
and children. I would like to say that this testimony reflects
my views, not the views of my clients.
The first thing I want to do is briefly define risk
assessment, even though a former witness did that for us. Risk
assessment is a process, a multi-step process within the
regulatory environment. Risk is defined as the probability that
any injury, disease or health effect, even something as
terrible as death, will occur from contact or exposure to a
chemical. I am going to limit my comments to chemical risk
assessment today.
It is a four-step process involving hazard identification,
dose response assessment, exposure assessment and risk
characterization. Each part of the process is very important in
being able to determine whether or not something we are exposed
to is truly going to harm us.
There is a large body of published, peer-reviewed
scientific literature available that speaks to the adequacy of
our current risk assessment process that is used by EPA to
protect human health. The large body of studies and information
out there speaks specifically to the health and the protection
of the health of sensitive human sub-populations, such as the
fetus, infants and children. I have reviewed and analyzed this
large body of information over the years I have worked as a
consultant, and I would like to speak just very briefly to a
few of the key points or principles that I think you can glean
as a scientist looking at this literature.
The first point, as I think everyone is aware, children are
not little adults. Age and stage of development are extremely
important to risk assessors. We use those things as
considerations in our process. Children, while not being little
adults, their sensitivity to chemical exposure is highly
dependent on the nature of the chemical. There are chemicals
where children are more sensitive and are the population of
concern for the risk assessment. There are chemicals where in
some cases it is a different population, the elderly, for
example, that may be of most concern. In some cases, children
can actually be less sensitive than the mature human adult to
the exposure to the chemical.
Age is not the only factor that contributes to differences
among humans in the response to chemical exposures. Gender,
genetics and health status are also very important, and in some
cases, more important than the age. Exposure, however, is one
of the most critical components in the process. We know that
there are a lot of data showing that children can be exposed to
a greater extent to chemicals in their environment, due to
things that they do daily in their environment. All of those
things are currently employed and used as part of the risk
assessment process. We do children-focused or child-focused
parts of our assessment when a child is the receptor or the
individual that is of concern to the risk assessment.
If you do an analysis and look at the studies overall, and
try to do what I call a weight of the evidence approach to
examining the published literature, you can see that the
methods that EPA currently uses for its risk assessment indeed
give a risk assessor some confidence that the developing fetus,
infants and children are being protected. Remember that the
methods we are looking at include consideration of differential
sensitivity, not only to toxicity, but also on the exposure
side.
Current risk assessment methods for chemicals employ
tiered-testing strategies as a common thing that we see today.
That is what the current regulations use. They allow the risk
assessor to look at the fact that resources are being focused
on evaluation of the chemicals of most concern and also looking
at the population of most concern. They allow you to prioritize
the chemicals for further testing. That is an important part of
the process.
So when I look at this data and also the regulations that
are currently in place, as a scientist, I believe that we can
have some confidence that we are protecting the fetus, infants
and children with the approaches that are currently in place.
This fact, combined with the fact that we know that hazard
is not the only part of the equation, but also we need to know
something about the exposure and the overall risk of the
chemical that we look at, that is an important part of the
equation is well.
Enforcing a chemical regulation is also a focus. I think
that is part of the process. When you look at TSCA, if
enforcement is done as can be done, indeed I think that the
chemical regulatory process can be complete and protective of
human health for all sub-populations.
I have a few seconds and I just wanted to make a couple of
comments to some of the things that I have heard before.
Senator Boxer. Actually, you have gone over. You have gone
31 seconds over, but if you want you can go another 30 seconds.
Go right ahead.
Dr. Plunkett. I just wanted to say that in some of the
comments that I have heard, and some of the studies and some of
the statistics that have been brought up by the other
witnesses, as a scientist, I am not aware that some of those
statistics are indeed true. I would encourage people on the
panel to use----
Senator Boxer. What statistics?
Dr. Plunkett. Some of the statistics about the rate of
cancer incidence increasing, the level that it has increased
over the years. I think if you look at the literature, those
numbers, at least the numbers that I am aware of are not
supported by the scientific literature, at least. I will end it
there.
[The prepared statement of Dr. Plunkett follows:]
[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
Response by Laura M. Plunkett to an Additional Question
from Senator Boxer
Question. Plunkety during the hearing, you stated that,
``as a scientist, I am not aware that some of those statistics
are indeed true. `` When I asked you which statistics. you
answered, ``Some of the statistics about the rate of cancer
incidence increasing, the level that it has increased over the
years. I think if you look at the literature. those numbers. at
least the numbers that I am aware of are not supported by the
scientific literature, at least. `` Please answer the following
questions concerning your statement:
Did you know that the National Cancer Institute. which is
part of the US National Institutes ofHealth. states: ``Over the
past 20 years. there has been some increase in the incidence of
children diagnosed with all forms of invasive cancer. from J1.5
cases per 100,000 children in 1975 to 14.8 per 100,000 children
in 2004."
Did you know that the America Cancer Society, which has
funded $3 billion in cancer research--including funding the
work of 42 Noble Prize winners--estimates that ``[s]ince the
early 1970's, incidence rates of... (non-Hodgkin lymphoma) have
nearly doubled. ''
Response. Senator Boxer, I am aware of the sources you have
listed above and in fact they are some
ofthesamesourcesIreferredtoinmyletter ofMay
1,2008toSenatorInhofewhereI suggested that statistics for
cancer incidence can be found in some reliable data bases such
as the NCI. In that letter. I mentioned two documents that
provide summaries of trends in cancer incidence over time
available from NCI (e.g., Ries, L.A.G. et al. (eds). SEER
Cancer Statistics Review, 1975-2005. National Cancer Institute.
Bethesda. MD. http://seer.cancer.gov/csr/1975--2005/, based on
November 2007 SEER data submission, posted to the SEER web
site, 2008; Ries, L.A.G. et al. (eds). Cancer Incidence and
Survival among Children and Adolescents: United States SEER
Program 1975-1995, National Cancer Institute, SEER Program. NIH
Pub. No. 99-4649. Bethesda. MD, 1999).
As I stated, both of these documents are reliable,
authoritative sources accessed by scientists when wanting to
understand trends in cancer incidence in the U.S. I believe
that review of these two documents reveals that the statistics
cited at the hearing on April 29th are not supported by the NCI
data. In general. cancer incidence overall has remained
somewhat stable over the last 30 years, with some regional. age
group. and racial variations. I would refer anyone interested
in citing a cancer incidence rate to those sources. with one
document specific to childhood cancers. I also believe that
these two documents would be good resources for the Committee
as they try to understand the incidence of cancer. As I do not
know where your statistics above are actually derived from, as
you have not provided me with the citations in your question
above, I cannot respond specifically to your values. I would
again reiterate, however, that the NCI indicate that the
overall incidence of cancer has remained somewhat stable and
that any trends in certain regional or age group statistics
must be carefully considered in light of Ms. Heather Majors
September 2, 2008 confounding factors such as changes in
diagnostic criteria or screening? factors that often are
responsible for purported increases.
Response by Laura M. Plunkett to an Additional Question
from Senator Inhofe
Question. Dr. Plunkett, there appeared to be some confusion
during the hearing about a comment you made about the ``rate of
cancer incidence increasing''. I believe you stated:
``Some of the statistics about the rate of cancer incidence
increasing, the level that it has increased over the years. I
think if you look at the literature, those numbers, at least
the numbers that I am aware of are not supported by the
scientific literature, at least. I will end it there. `` I
believe you were making the point that the rate of increase may
not be as great as others suggested, not that the rate was
decreasing. Is this correct and please elaborate.
Response. Senator Inhofe, you are correct in your
suggestion above regarding my statements. During the hearing it
was erroneously asserted that I had testified that cancer rates
in the U.S. are decreasing. What I was actually addressing in
my testimony and answers to questions was the need to assure
that any statistics on disease incidence that were presented at
the hearing be based on sound science and not merely statements
made for impact without a basis in actual scientific data.
During the hearing I was concerned and raised questions when I
heard statistics being mentioned that based on my experience,
were not reflective of the actual incidences of cancer and the
changes in sperm count in the U.S.
It is important to realize that data on something such as
cancer incidence are complex. Statistics can be reported based
on yearly incidence, incidence over time, incidence broken out
by sex, age at diagnosis, mortality, etc. A scientist must
consider whether any statistics collected are representative of
the population of concern. The best source of such data for
describing the U.S. population would be data collected in the
U.S. Such an authoritative source would be the National Cancer
Institute (NCI), which is a part of the National Institutes of
Health, Department of Health and Human Services. Although I
have not had time to do an exhaustive search of all the data
available, there are several summaries of trends in cancer
incidence over time available from NCI (e.g. Ries, L.A.G. et
al. (eds). SEER Cancer Statistics Review, 1975-2005, National
Cancer Institute. Bethesda, MD, http://seer.cancer.gov/csr/
1975--2005/, based on November 2007 SEER data submission,
posted to the SEER web site, 2008; Ries, L.A.G. et al. (eds).
Cancer Incidence and Survival among Children and
Adolescents: United States SEER Program 1975-1995, National
Cancer Institute, SEER Program. NIH Pub. No. 99--4649.
Bethesda, MD, 1999). Both of these documents are reliable,
authoritative sources accessed by scientists when wanting to
understand trends in cancer incidence in the U.S. Review of
these two documents reveals that the statistics cited at the
hearing on April 29th are not supported by the NCI data. In
general, cancer incidence overall has remained somewhat stable
over the last 30 years, with some regional, age group, and
racial variations. I would refer anyone interested in citing a
cancer incidence rate to those sources, with one document
specific to childhood cancers.
With respect to sperm counts in the U.S., there is no one
source of data that I can point to for reference. However, one
authoritative source, the World Health Organization
International Program for Chemical Safety (WHO/IPCS), did
perform a comprehensive review of the issue of endocrine
disruption (including sperm count issues) in 2002 (IPCS. 2002.
Global assessment of the state-of-the-science of endocrine
disruptors. Geneva: World Health Organization). The WHOIIPCS
concluded that with respect to the hypothesis that there may be
a global reduction in human semen quality (including sperm
count) that might be related to environmental exposures to
chemicals acting as endocrine active substances, there is not a
global trend for declining semen quality that can be identified
based on considering all of the available data. They found that
although some studies showed declines in certain regions or
cities, other studies found no evidence of such decline,
suggesting there may be regional trends but not a global trend.
Therefore, this authoritative source does not support the
statistic quoted in the hearing related to sperm count
declines.
As I also stated in my previous letter, I strongly believe
that science should not be used as a political tool to support
one position or another, but should be used as part sofa
decision making process. In this case, it is not sound science
to use statistics that are not reflective of the appropriate
population, or are reflective of only one study when there is
body of evidence to consider.
Senator Boxer. We will get--it depends on the type of
cancer, but we will get that information into, we will go to
the Cancer Institute doctor and we will put those in the
record. So wherever that will fall.
Dr. Lynn Goldman, we welcome you, M.D., Chair, Program and
Applied Public Health at Johns Hopkins, former Clinton EPA
Assistant Administrator for Pesticides and Toxic Substances.
Also a pediatrician, I understand. We welcome you, a majority
witness. Go right ahead.
STATEMENT OF LYNN R. GOLDMAN, M.D., M.P.H., PROFESSOR,
ENVIRONMENTAL HEALTH SCIENCES, JOHNS HOPKINS UNIVERSITY,
BLOOMBERG SCHOOL OF PUBLIC HEALTH
Dr. Goldman. Chairman Boxer and members of the Committee, I
really appreciate your interest in this issue. I think that the
regulation of chemicals by EPA is a very important area.
In 1976, when the Toxic Substances Control Act was passed,
there were great hopes by Congress for what it might do.
Unfortunately now, 32 years later, one must acknowledge that
this Act needs to be revised, in particular, to protect
children. Chairman Boxer, I know that you have had a major role
in legislation to protect the health of children. Your
colleague, Senator Lautenberg, talked about the Kids Safe
Chemical Act, which I think has been a wonderful effort.
I understand, as a former regulator of the chemical
industry, the way that chemicals play a vital role in the
economy. They are very important in our society and I would not
underestimate that. But I think I also understand that strong
regulation is needed to assure the health of all our citizens,
especially our children.
Today I am here to address the concerns about EPA's IRIS
program. What is this program about? It was mentioned earlier
that the dose makes the poison. What IRIS is about is
establishing what that dose is that makes the poison, so that
everybody in society, whether it is regulators, doctors,
States, industry, will know what EPA's views are about that
does. I don't think any of us here today are saying that any
level of exposure to any chemical is of concern. We want to
know what the levels that are safe and what levels are of
concern. That is what IRIS is all about.
I have been studying formaldehyde, and I think it is an
example that helps to understand about why this is important.
You know that formaldehyde is used extensively in the
manufacture of wood and wood products. For many years, it has
been considered to be a probable human carcinogen. But in 2006,
IARC, the International Agency for Research and Cancer, made a
determination that formaldehyde is known to cause cancer in
humans, does actually cause cancer in humans. This is a very
difficult threshold of evidence to meet for any chemical.
And the truth is that nearly everybody but the United
States has taken strong regulatory action on formaldehyde. The
State of California, the European Union, Australia, Canada and
Japan have mandatory standards that are several fold stronger
than the U.S. Government's voluntary standards for formaldehyde
in wood products.
Since 1997, the EPA has been trying to reassess
formaldehyde. In 2004, this process was brought to a halt.
Basically, EPA's political leadership was convinced that new
science was right around the corner and they should delay a new
IRIS listing for formaldehyde. At the same time, the Chemical
Industry Institute of Toxicology, the CIIT, published its own
risk assessment, which would say that formaldehyde standards
should actually be weakened and not strengthened.
It was fairly unprecedented. In 2004, when EPA's Air Office
issued its new hazardous air pollutant standard for
formaldehyde, it actually incorporated the CIIT assessment
without any concurrence from EPA's scientists or from EPA's
science advisory board. Now, I should say that rule was struck
down in 2007 for procedural problems, other problems with the
rule. But I think that this shows how, even in EPA's actions,
this lack of progress with IRIS has been a problem.
Then in 2005, Hurricanes Katrina and Rita flooded the Gulf
Coast, and as you know, FEMA provided 120,000 travel trailers
to the victims of those storms to serve as temporary housing.
Unfortunately, these trailers contained unacceptable levels of
formaldehyde. I think the story is very familiar to all of you,
including the slow response by the Federal Government, the
tragic consequences to the people who were living in those
trailers, all of which in my view would have been unnecessary
if EPA had done the right thing in the first place in terms of
moving forward an appropriate scientific assessment.
My point is that when you suppress this kind of information
about what is the dose that makes the poison, there are serious
consequences. We need to have an EPA whose scientists are free
to communicate to us about risks. That is very, very important.
When they are not free to do so, when there are impediments,
when they are held hostage to these processes that go on
interminably, the public's health does and will suffer.
It is a complex and challenging process to do these IRIS
reviews. It is also difficult to peer review these. The process
of peer review needs to be done----
Senator Boxer. You will have to conclude.
Dr. Goldman. I will. It needs to be done in a scientific
process and not through a process that is basically an
invitation to back door involvement by parties who might be
affected by the scientific assessment. I think that is what we
have here.
Thank you very much.
[The prepared statement of Dr. Goldman follows:]
[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
Senator Boxer. I think that is the nub of what we have
here. Thank you.
Here is what we are going to do. I am going to give Senator
Whitehouse and Senator Barrasso 7 minutes each to ask their
final questions and sum up, and then I will take my turn and
then we certainly thank this panel and the one before. This has
been a very important hearing.
Senator, 7 minutes, please.
Senator Whitehouse. Thank you very, very much, Chairman.
Let me start by asking Dr. Goldman about the, you described
it as a back door process or a back door that the IRIS program
creates in the process for influence by people who aren't
proper scientists. I agree that it appears to deliberately
create a vector for political interference. To what extent it
will be used or not is open, but epidemiologically, you don't
want to create that kind of vector, if you can, even in a
political environment.
But in response to that, Mr. Gulliford suggested that OMB
had scientists on staff and that raised the implication that
what is happening here with OMB is that they are adding to the
science knowledge that EPA possesses. Based on your experience,
how would you rate the scientific, particularly the science of
chemistry, knowledge that is contained within OMB compared to
that is contained within EPA with respect to the chemical
process and its approval for use around humans?
Dr. Goldman. For any one chemical, it is difficult to
construct a panel of scientists who are qualified to peer
review an assessment like the IRIS assessment. I cannot think
of a single small group of scientists who are qualified to peer
review each and every one of those, in addition to all the
other science that the scientists at OMB supposedly are
reviewing. No matter how good they are, it is not possible for
them to have the depth and the breadth that you need to do that
kind of review.
How you add value through peer review is through something
like the Science Advisory Board that EPA already has, which, by
the way, is done out in the open. Those reviews are in the
sunshine. Anybody can come and contribute, industry can
contribute, others can come and contribute. And their arguments
are considered on the merits, in terms of the science they are
presenting. It is not political science. This is about science
and the science advisory board process is the best way to
accomplish that.
Senator Whitehouse. Are you comfortable with the IRIS
process as proposed at all?
Dr. Goldman. Not at all. And I am very disturbed by the GAO
report and seeing that EPA has increased the resources for that
program fivefold over the last several years, with what looks
to me to be about a four to fivefold decline in productivity.
And now they are proposing to put more bells and whistles on
the process. If nothing else, it is just poor management. There
is very little output. More than half of the listings are out
of date. And this is information that everybody needs,
including industry.
Senator Whitehouse. You mentioned formaldehyde, which is of
particular interest. The Chairman knows very well my wife, I am
a very over-married human. And as she well knows, my wife is a
trained scientist. As a result of her education and the work
she did as a marine biologist, she has had substantial exposure
to formaldehyde. So that is, you ring a bell with me when you
talk about formaldehyde.
As I understood it, you said that the EPA began its process
to evaluate the carcinogenic effects of formaldehyde back in
1997. And it wasn't until 2004 that the process was closed to
completion. It was then derailed by a finding, I guess by the
Administrator himself, that there was new science around the
corner.
Was there any new science around the corner, or was he just
waiting for the CIIT assessment? Was there, in the world of
this science, was there some sort of tectonic shift that took
place? Was there a new development that emerged?
Dr. Goldman. Nothing has emerged since then. You are
married to a scientist, so you know there is always new science
around the corner. What one has to be committed to is periodic
reevaluation, so that new science is incorporated. But no,
nothing new has emerged since 2004, nothing.
Senator Whitehouse. And then you said it was struck down in
2007. Struck down by courts?
Dr. Goldman. The rule was struck down, but not because of
the risk assessment, but because of other things, such as some
of the exemptions they tried to include.
Senator Whitehouse. The Chairman has hosted hearings on the
EPA batting record in the courts of this Country with their
theories of why various anti-environmental policies should
stand up. But here we go again. So as I summarize it, here we
are in 2008. They started in 1997. Because of all this various
folderol, we are effectively no place right now with respect to
formaldehyde. How would you describe where we are in the
process right now with respect to making a conclusion as to
whether it is carcinogenic and what steps should be taken to
protect public health?
Dr. Goldman. I think we have to rely on the international
assessment that came forth from IARC in 2004. We still don't
have a voice from EPA on this. As far as I can tell, we are
going to wait a long time before we will hear from EPA unless
something is done to change this process.
Senator Whitehouse. Thank you.
Dr. Giudice, I would like to give you the opportunity to
respond to Dr. Plunkett, who suggested in her testimony that
the statistics that you shared with us were not supported by
data. Just based on your resume, as the professor, indeed,
Chair of the Department of Obstetrics, Gynecology and
Reproductive Sciences at the University of California in San
Francisco, I am not inclined to believe that you have made up
statistics here in testimony before a Senate Committee. But I
would like to give you the chance to buttress your assertions
in light of her comments.
Dr. Giudice. Thank you. I appreciate that opportunity.
There is a reference by Bray and colleagues at the
International Journal of Cancer in 2006, volume 118, pages 3099
on trends in testicular cancer incidence. This is very recent
and I would suggest that our colleagues look at that particular
article.
I am happy to provide the Committee with the written
references for the other statistics that I quoted. Thank you.
Senator Whitehouse. Madam Chair, thank you very much.
Senator Boxer. Thank you.
Before I call on my colleague, I want to put two things in
the record, or three things. First, letters from more than 50
national, State and local public health and environmental
organizations expressing their opposition to the new
interagency policy on IRIS, and also I am putting in, if there
is no objection, recent news reports on this issue. Then
second, Senator Whitehouse before you leave, this is in
reference to your question and also the assertion by Dr.
Plunkett that cancer is going down.
How have childhood cancer incidence and survival rates
changed over the years, National Cancer Institute, an increase
over the past 20 years of children diagnosed with all forms of
invasive cancer, from 11.5 cases per 100,000 in 1975 to 14.8
cases per 100,000 children in 2004. And finally, also from the
Cancer Institute, lymphoma, an estimated 74,000 new cases of
lymphoma will occur in 2008. Since the early 1970's incidence
rate for non-Hodgkins lymphoma has doubled. Just wanted you to
know that before you left.
[The referenced material was not received at the time of
print.]
Senator Boxer. Senator.
Senator Barrasso. Thank you very much, Madam Chairman. I
have two documents I would also like to read into the record,
if I could, one from Synthetic Organic Chemical Manufacturers
Association and another from the National Petrochemical
Refiners Association.
Senator Boxer. Without objection, Senator.
[The referenced materialwas not received at the time of
print.]
Senator Barrasso. Thank you.
Ms. Gellert, I appreciate your comments and your testimony
as you are a cancer survivor, with placental cancer. My wife is
a cancer survivor of breast cancer, which is obviously much
more common, one in eight women, than placental cancer. Dr.
Giudice, you are the professor. Placental cancer is fairly
rare, isn't it?
Dr. Giudice. Placental cancer is very rare, yes. It is much
more common in Asia than it is in the United States. And the
prevalence here I believe is something like 1 in 10,000 to
15,000.
Senator Barrasso. I think it is Taiwan with the greatest
prevalence that I have studied, is it thought to be
environmental in Taiwan?
Dr. Giudice. It is unclear what the etiology is.
Senator Barrasso. All right. I was curious how that all
came about. Thank you.
I notice that the two of you work pretty closely together.
You are on the board of advisors of the UC San Francisco
Medical center--no? All right. Then I must have a different
Annette Gellert that is listed for the WELL Network.
Ms. Gellert. I am a previous board member of the Obstetrics
and Gynecology Research and Education Foundation at UCSF. That
was a previous position. I am not currently on that board.
Senator Barrasso. You are currently off the board.
Ms. Gellert. I actually came to know about that board when
I was at UCSF getting treated for the molar pregnancy that I
had. My point was that I really, I don't know what caused it. I
want to know what caused it. I want to know, I want more
information so that I can, I want to know about my husband,
too.
Senator Barrasso. With his bladder cancer? My best thoughts
are with him.
Ms. Gellert. Yes. The known cause of that is industrial
chemicals from every source that I could find.
Senator Barrasso. And other causes, there are other----
Ms. Gellert. Well, smoking, and he has never smoked a day
in his life. Two risk factors are mentioned, one is smoking and
the other is industrial chemicals.
Senator Barrasso. OK. And then I understand, Doctor, that
you are also an honorary board member of WELL Network?
Dr. Giudice. I am. I just became, and when Ms. Gellert was
on the OB/GYN Foundation Board at UCSF, this is close to 20
years ago, and I joined UCSF two and a half years ago.
Senator Barrasso. Thank you.
Dr. Plunkett, I think we had kind of a back and forth,
people responding to differences. Are there additional amounts
of my time you would like to use to help clarify some of these
matters?
Dr. Plunkett. I just wanted to State that I am not
asserting that cancer rates are going down. What I was trying
to comment on was the fact that actually, I heard Ms. Gellert
mention some statistics on rates and incidence. I had not, I am
not aware of those particular numbers. I am concerned because I
think there is a perception of the lay person and the public,
and there is information out there that the scientists are
aware of, and maybe we as scientists need to be better at
getting that information out, so that the public is aware of
what the real risks are, and what true incidence rates, what is
the real incidence rate, how do you calculate it, how do you
determine it, versus the numbers that may get thrown around in
the popular press. That is all. That is really what my comment
was about.
I am not aware of the data that would support some of the
numbers that were coming out. Certainly if there is such data,
I would love to see it. I am just not aware of it. I am also
not aware of the fact that the incidence rates have been going
up to the level that has been asserted. That was the comment or
the position I was trying to take.
Senator Barrasso. You said in your testimony that the EPA
currently has in place some methods for considering infants and
children as separate exposed populations, apart from adults,
allowing a risk assessment to consider and account for
differences in exposure patterns. Could you elaborate a little
bit on that?
Dr. Plunkett. Yes. In the current methods that are used,
where you do a risk assessment, you are looking at all the
potential populations that can be contacted or exposed to the
product. And if you have a product or chemical where you are
worried about child exposure, such as if you had an infant, a
bottle for an infant or you had some other product that the
child might be contacting routinely, you can do child-specific
exposure assessment on that. In addition to that, in the
toxicity evaluation part of the risk assessment, for many, many
chemicals you have data that has been collected in developing
animals, reproductive and developmental toxicity studies, where
you actually can assess what were the direct effects on a
developing organism from exposure to that chemical.
I know there are many chemicals that may not have that kind
of data. But most of the ones we are talking about that have
been raised at issue in this hearing, as I have heard it, are
ones where that data is available.
Senator Barrasso. Mr. DeLisi, you talked about the program
in Europe, the REACH program. Is there a lot of hazard and
exposure data available that has been gathered from that on
different chemicals already?
Mr. DeLisi. Nothing has been gathered yet. The pre-
registration period starts on the 1st of June, then you have
until 2010 for more than a thousand tons a year of commerce and
2013 for a hundred to a thousand and then 2018 for less than a
hundred tons.
Senator Barrasso. If we don't have any data yet from that
REACH program, is it right to make comparisons between TSCA and
the REACH program?
Mr. DeLisi. I don't know how that would be possible.
Senator Barrasso. I want to ask about some potential, Mr.
DeLisi, in making the change in TSCA so that it shifts the
burden of proving safety from the EPA to manufacturers. Would
you recommend shifting that burden and how will that affect a
manufacturer's ability to meet its needs of customers?
Senator Barrasso. The burden needs to continue as it is,
which is really shared. I was at a REACH conference last week,
because REACH does talk about banning products, and frankly,
the thing that most startled me was a representative of Rolls
Royce trying to figure out how they could make a jet engine
altogether without the use of nickel compounds, which could
potentially occur in the EU, that nickel compounds would be
banned. He literally said that, we can't figure out how to keep
a jet engine together without the use of those kinds of
materials.
Senator Barrasso. Thank you, Madam Chairman.
Senator Boxer. Well, we are going to close this panel out,
and we have a few comments, a couple of questions.
This has been a really important and far-reaching hearing.
I want to thank each and every one of you. I think it has been
good to have both sides on this panel. And frankly, on the
other panel as well, the GAO saying that they investigated the
EPA and found out politics is taking over the program, and EPA
saying, oh, no, nothing could be further from the truth. Well,
let's let the public judge and let's let my colleagues judge.
But let me tell you what is going to happen, Mr. DeLisi and
Dr. Plunkett, Ph.D. If we don't see action out of the EPA on
listing these harmful chemicals, not only listing them but
regulating them, Congress is going to do it. Senator Feinstein
offered an amendment with me to ban phthalates. It passed
overwhelmingly. You can see where Senate Whitehouse is coming
from on formaldehyde.
So don't think because you may be looking at this process,
the weaker it gets, the stronger we are going to get. Because
no Senator in the light of day, I shouldn't say no, most will
not be able to take the heat of these dangerous chemicals.
People are not stupid, they are smart, they understand, they
see what is happening to their families. No one can tell them
what is happening to their families, because they see it.
So no one can say, oh, it is safe and cancer is going down
or whatever you said, I am checking on your words. The fact is,
we know the facts. Childhood cancer, up. I mean, it is a fact.
So I just want to thank the doctors on the panel, the
medical doctors on the panel. You took an oath to do no harm.
And what you are doing through your work, your active work,
which I praise so much, what you are doing is making sure that
we are not harmed.
And what is so intriguing about this hearing is that there
are several issues raised, which is what we wanted. One is the
current system, the way we regulate chemicals now and how it
has failed us and how they have come up with four decisions
when they were supposed to come with a hundred in the last 2
years.
So it has failed us, because the Administration has
informally put into place the change in the IRIS program where
they are allowing people to sit around a table secretly and
give their views. And they have tainted and corrupted, and I
use my words advisedly, they have corrupted the process of risk
assessment. And the point is, it is not going to work, because
the people won't allow it to happen.
And you know, we met with a chemical company the other day
who said that they are, and I am going to just tell you what
happened, and I will direct this to Mr. DeLisi. We met with a
chemical company that said they have invented substitutes for
toxic chemicals, such as insulation without formaldehyde. And
without strong regulations on the chemicals that present a
risk, there is not a strong market for the safer product.
So would you agree that sometimes regulation will spur
invention, the genius of America, which is what Annette Gellert
talked about, working with the private sector? Why is it my
colleagues on the other side paint this picture of, every time
we want to help the people of America get safer, oh, we are
going to hurt the economy? That has never been true with
environmental regulation. Never. We have had green industries,
we have had green jobs. This is the scare tactics. So people
get sick and they die and oh, we can't do anything about it,
because it is going to hurt people's jobs. Well, you know, if
you are really sick and you can't breathe, you can't come to
work. Pretty basic.
So Mr. DeLisi, I want to ask you, don't you think that when
there is reasonable regulation that it presents an opportunity
for business to come up with a safer product that you could
then export to Europe, where there is obviously going to be a
huge market for greener products? What do you think?
Mr. DeLisi. Senator, unfortunately, I think it is a two-
edged sword. My Senator, Frank Lautenberg, this morning
mentioned DDT. DDT is still in use in sub-Saharan Africa and
lots of places, protecting people from the ravages of the
mosquito-borne diseases. I would not want to be a regulator----
Senator Boxer. OK, I am not asking you about DDT, because I
know that story is always brought up. I am asking you about
this man who came in from a chemical company and said they are
ready to roll with a substitute for formaldehyde. I am asking
you, yes or no, is there ever a case where reasonable
regulation will lead to better, safer products? Yes or no?
Mr. DeLisi. It can.
Senator Boxer. Good.
Mr. DeLisi. But if the cost of that insulation that he is
producing is so large that nobody can afford it, that is a
down, that is a problem for the consumers.
Senator Boxer. Yes. But if I told you that your kid being
exposed to certain levels of formaldehyde is going to get lung
cancer, that the chances are, it is a very good chance, don't
you think that is something we ought to move on and allow these
substitutes? Don't you think that people in the Katrina housing
there deserve to have accommodations that were free of
formaldehyde? Don't you think?
Mr. DeLisi. I am not an expert in formaldehyde, but if that
has been proven, absolutely.
Senator Boxer. Good. Well, we are working on it, here, we
are getting there. I love agreement.
Well, let me just say, again, do we have this? OK. All
right. So we are going to put a lot of studies in the record,
we will leave the record open for a week. And in summing up,
here is where I think we are. We have an IRIS process that is
the basis for many of our various environmental laws. That is
how they, the Clean Water Act, the Safe Drinking Act, the
Superfund, TSCA, they rely on--did I leave anything out?--Clean
Air Act, they rely on the IRIS program. So IRIS cuts across.
Now, we know the IRIS project has been corrupted. And the
reason we know it is the GAO did an investigation and they are
telling us that already, even without the new system in place,
in effect, everything has basically stopped. And instead of
listing and regulating 100, not listing, scratch that, instead
of regulating 100 chemicals over 2 years, they have regulated
four. So we are in a crisis. Annette Gellert was right, she
used that word. We are in a crisis.
If this goes forward, this process that Mr. Johnson, who
refused to come here, somebody said no wonder he went to
Australia, he doesn't want to sit across from me, I totally get
it. But the fact of the matter is, he has a responsibility to
be here and defend himself on this. This is a nightmare. This
is a scandal.
So we now have a circumstance where we are going to see a
formalization of a process that puts politics in the center of
regulating chemicals as Dr. Goldman alluded to, instead of pure
science. This is a travesty. And it is happening under our
noses.
We are not going to stand for it. Either we are going to
change things in the election or we are going to start banning
these chemicals. Because there isn't one colleague that I know
who is going to be able to stand the heat when there is proof
about these chemicals.
Now, I know Dr. Plunkett, you have defended people, your
firm has, when they are sued, is that right?
Dr. Plunkett. Most of my litigation work currently is in
plaintiff's litigation, actually, not in defense.
Senator Boxer. OK, so you bring suits against chemical
companies?
Dr. Plunkett. I don't bring suits. I have been an expert
witness in litigation where suits have been brought against
mainly pharmaceutical companies for injuries related to----
Senator Boxer. So you have testified for the injured party?
Dr. Plunkett. Yes, I have.
Senator Boxer. Or for the company?
Dr. Plunkett. For the inured party, in most cases.
Senator Boxer. You do. So your firm is bent toward making
sure that people who are injured by chemicals have a right to
sue, and you come in and you testify on behalf of the injured
person, is that correct?
Dr. Plunkett. I act as an expert witness, to tell you what
I do, I act as an expert witness, provide pharmacology and
toxicology and FDA regulatory testimony related to the risks
and hazards posed by a drug and whether or not that drug could
have caused the injury in an individual.
Senator Boxer. OK, well, I have some confusion, because
your firm advertises, I have seen the advertising, that you
would represent business in defending them. And you are saying
you defend the plaintiffs, the harmed ones.
Dr. Plunkett. I have worked on both sides. I have also done
litigation where I have worked on behalf of industry as well.
But in expert witnessing, currently in my litigation practice,
all of my cases are plaintiffs cases at this point in time.
Senator Boxer. OK, but, this firm----
Dr. Plunkett. Integrative Biostrategies, yes.
Senator Boxer. So this is wrong, it says it represents
product liability, toxic tort, heavy metals, petrochemicals,
pesticides and that is, my understanding is that they support
the companies. That is not right?
Dr. Plunkett. I do work on behalf of chemical companies in
risk assessment and regulatory issues, yes.
Senator Boxer. Oh.
Dr. Plunkett. I have also worked on behalf of individual,
for example, cities, other entities outside of industry. So I
do both of those things.
Senator Boxer. So cities that are sued?
Dr. Plunkett. No. It is not all litigation work. In fact--
--
Senator Boxer. Let's give an example of a city you have
represented.
Dr. Plunkett. For example, I have not represented, I have
worked on behalf of a small city in Texas where there was a
lead battery recycling facility located in town, right within
the town. I worked with the city to help do a blood lead study
on whether or not the industry was impacting the residents. I
designed the study and helped implement the study for the city.
So in that case, I was working on behalf of the children and
the families within the city to determine whether there was a
risk to their health.
Senator Boxer. Well, good for you. Because then you ought
to know about childhood cancer rates a little more.
Dr. Plunkett. I----
Senator Boxer. Here is the thing. We are dealing with life
and death here. We have a witness who is experiencing a spouse
who has bladder cancer. She said the two causes that she has
been able to learn, because they don't know why, are smoking,
which he never did, and exposure to industrial chemicals. We
need to find out these things. We need to know, frankly. Our
Government needs to know, so you don't have to go off to Texas
and figure out what this, I mean, we ought to have the
information of what these batteries do.
Dr. Plunkett. I would agree with you, Senator, that we need
to know about the chemicals. My only point, the reason I am
here today is to say that I believe there are risk assessment
methods currently in place that allow us to determine which
chemicals truly are risks, based on hazard information which we
have, but also exposure and the actual information from the
science on the responses in individuals.
Senator Boxer. Right. And I will tell you, what we have in
place is the IRIS program.
Dr. Plunkett. We have more than that in place, I would
argue.
Senator Boxer. That is the basic, well, you could argue it.
But the fact is, every single agency has told us that the IRIS
program is the program that is the basis for their decisions,
OK? So the IRIS program is the basis for regulation under the
Clean Air, Clean Water, and Superfund and all the things that I
mentioned before.
So the IRIS, the integrity of that program is at stake
here. That is why, when the GAO tell us the program is a shadow
of its former self, now, to get to the issue of REACH is very
important. Because, Mr. DeLisi, I want you to explain something
to me. My understanding is a lot of chemical companies do
business in Europe. Is that correct, would that be your
understanding?
Mr. DeLisi. Yes.
Senator Boxer. And they will have to conform with REACH, is
that correct?
Mr. DeLisi. Or they can make a decision to stop doing
business in Europe.
Senator Boxer. Exactly. And what do you think people will
do? Do you think they will walk away?
Mr. DeLisi. Some will.
Senator Boxer. Well, I would argue they won't walk away. I
will argue that they will want to, because this is a global
marketplace. And with the dollar falling as it is, this is the
moment where our business are really, at least beginning to see
an increase in their exports. So I would argue that they would.
And I would further say, going back to my initial point,
that when we have this concern, and it is expressed in
legislation, you are going to have an impetus for these
substitutes. Now, you are very right, maybe they will cost a
little more. I would submit to you, if you ask the American
people, if you could reduce the rate of childhood cancer, we
could go into what those cancers are, by taking the following
steps, having to pay 35 cents more for a solvent, or a dollar
more for a different type of cleanser, I would be people would
be glad to do that.
So from my perspective, I think it is very shortsighted for
business to put their head in the sand and act as if nothing is
going to change. Because here is my point. If we don't see a
coming together here and I will get back to what Annette
Gellert said, which is, working together with business and
Government and the non-profit community, if we don't see that
happening, I am just saying, colleagues of mine are going to
take matters into their own hands and you are going to see
banning of these chemicals and banning of these products. And
you will not know what is going to hit you next.
So I think it is in the best interest of business to work
with us in a way where we do have an open, transparent process
here, where we don't have the regulation of a chemical such as
formaldehyde get bogged down, as Dr. Goldman said, when we were
just there at coming up with the regulation, Mr. Johnson pulled
it down. That is not going to sit well, and you are going to be
far worse off. You are going to have no certainty because you
are going to have people going to the floor of the Senate
saying, my community, so many people got this type of cancer.
And you are going to really have more of a problem.
So I would urge us to work together. I think the message of
the Wellness Foundation, is it the Foundation?
Ms. Gellert. The WELL Network.
Senator Boxer. The WELL Network. That is a great message.
We are all in this together. This shouldn't be one side arguing
with another. We have everything to gain when we have safe
products. We have a confident community that won't start
boycotting certain products. And I just think do no harm is our
first thing we should think about, do no harm. But second, make
things better.
I think we ought to look at what Europe is doing. I think
we ought to realize that it is in the best interest of our
businesses to learn to work with these restrictions and see how
we can have a system, frankly, that isn't different. Because I
think that another thing Annette Gellert said is right on the
mark, we don't want America to be the dumping ground for
dangerous products.
Because here is what is going to happen, I will tell you
right now, our people will start importing products from Europe
in numbers. And by the way, it will be a big business. Somebody
will get a license, they will bring in these safe products and
you will not be able to compete because the American people
understand that some of these chemicals are dangerous. And if
they have an opportunity to buy a green product, they are going
to do it.
So I think this could be a win-win for business if we have
a little bit of a different attitude. Otherwise, you are going
to have competition from abroad you never thought you had. I
just think that is not good for business and it is not good for
our people. So this has been a heart-felt hearing. I really
thank all of you for being here, all of you, with your
perspectives. I respect all the perspectives, but I think at
the end of the day when our people are healthy, we are a better
Nation for it.
Thank you very much, and we stand adjourned.

Statement of Hon. Benjamin L. Cardin, U.S. Senator
from the State of Maryland
Madame Chairman, thank you.
The mission of the Environmental Protection Agency is to
protect human health and the environment. The Integrated Risk
Information System (IRIS) Program is a manifestation of that
part of the EPA's mission which includes the evaluation and
regulation of toxic chemicals.
With over 500 chemicals listed, and over 9,000,000 queries
to the IRIS data base, IRIS is a valuable resource both within
the U.S. and around the world in understanding the potential
human effects that exposure to the listed chemicals might
cause. The quantitative information contained in IRIS allows
IRIS to be a component in the regulatory process of many states
and even other countries. The regard with which this data base
is held is a tribute to the tireless efforts of EPA scientists
in evaluating the risks of the listed chemicals. In order to be
both useful and credible, the process to list a chemical in the
IRIS data base must be unbiased, science-based, timely, and
transparent.
In the last few years, despite increases in IRIS personnel,
a backlog of IRIS assessments have developed. This backlog is
due, in part, to new OMB-managed, interagency reviews and due
to delays in completion of assessments to await new research.
Earlier this month, the EPA released a revised assessment
process for IRIS. This revised process concerns me as it will
allow far less transparency into the decision making process.
The new assessment process conflates the EPA's science
position on an assessment with the EPA's science policy
position. Assessment findings should inform policy, not be
informed by policy.
Finally, this revised assessment process continues the
recent practice of OMB's having a role in the process as well
as establishing a new, interagency review process for IRIS.
This change potentially compromises the integrity of IRIS by
allowing those agencies that may have a stake in the EPA's
assessment be able to influence that very assessment.
I am pleased to welcome Dr. Lynn R. Goldman, a professor of
environmental health at the Johns Hopkins Bloomberg School of
Health. Dr. Goldman has served as EPA Assistant Administrator
for Prevention, Pesticides and Toxic Substances. Dr. Goldman's
work in reducing the risk of chemicals and pesticides to the
health of the public in general, and children in particular, is
noteworthy.
I look forward to hearing Dr. Goldman's testimony and that
of all of the other panelists today as we conduct this
oversight hearing into EPA's toxic chemical policies.
Public health and environmental policy decisions must be
rooted in objective scientific assessments. These assessments
must be timely and made using the best practices possible.
Thank you Madame Chairman.
